Weir expands digital capability with acquisition of AI-focused SentianAI

Weir has acquired Sweden-based SentianAI in a move that, it says, will accelerate its technology roadmap and expand its digital capability to provide enhanced productivity and sustainability offerings to customers. SentianAI is a developer of artificial intelligence-based solutions that optimise performance in minerals processing. Founded in 2016, it is based in Malmö and has a team of software developers and data scientists.

The software that SentianAI develops uses advanced AI algorithms that continuously learn and adapt to the dynamic processes within a mine, providing continuous improvement and optimisation over time, Weir says. Jon Stanton, CEO of The Weir Group, said: “Digital technology has an important role in helping address the challenges of declining ore grades, production efficiency and CO2 emissions for our customers. SentianAI’s advanced software solutions complement and will bridge our Synertrex® and Motion Metrics™ technologies well. Together, these will enable us to provide holistic performance monitoring and optimisation for smart, efficient and sustainable mining.”

Earlier this year, SentianAI and Xore Analyzers formed a strategic cooperation to combine XORE’s XRF analysers, which provide real-time data on metal content, with SentianAI’s machine-learning technology, which adapts to variations in ore properties. The pact, SentianAI says, could allow mining operations to improve their recovery rates and overall efficiency.

IM interviewed SentianAI Founder and CEO Martin Rugfelt last year on its technology and approach. He said it already had a flotation project targeting increase of recovery rate but also the stabilisation of the circuit performance. It was also working on optimising a crushing and grinding circuit with the primary goal of an increase in throughput.

When asked how its approach differed to other AI approaches in industry he commented: “A lot of the ‘traditional’ AI systems we see are actually AI toolkits/platforms that are sold on the basis that the customer can create AI logic that they need to solve specific problems without having to understand the detailed data science. Unfortunately, without knowledge of the underlying AI and data science, creating AI for complex systems eg control processes is very difficult. As a result, many ‘traditional’ AI systems are abandoned after purchase. Sentian has taken a different approach. Our SentianController is explicitly designed to optimise control of industrial processes, so when customers buy it, they already have the AI algorithms developed and tested for the complexity of control system optimisation. It is effectively a point solution that means you do not need a large data science team to build and run the AI solution.”

He added on the underlying technology: “SentianAI has worked for many years to select the best algorithms and refine how these algorithms work to deliver a unique AI system that has been designed to control and optimise industrial processes. This is very complex and requires some of the latest technologies in AI to be able to achieve the necessary control. We have also developed a system that can uniquely be applied in stages as data quality improves and operator confidence increases – going from making recommendations to fully autonomous control at the speed our customers want. This allows customers to build confidence before committing to fully autonomous control. We have chosen not to patent our solution as it would have exposed the technology, however, we would argue it is very unique.”

He said the system is also capable of self-adaptation, which can be achieved when you have both the right data and the right AI models. “The AI creates a dynamics model that is made from both historical and ‘live’ operational data. It can then choose the set of control parameters that deliver optimum performance towards a specific goal, eg maximum production for minimum energy usage. In comparison to traditional supervisory control systems it adapts to changes in the process. For example, if the process changes for some reason, leading to new data points, the AI incorporates these into its model, new predictions are made, and new control parameter settings are used. New goals can also be set, resulting in SentianController choosing the best control parameters to achieve those goals.”

CEEC-GlobalWaterInitiative

Weir and Agnico Eagle sign up to CEEC Global Water Initiative

CEEC International, an independent global not-for-profit committed to accelerating the adoption of eco-efficient minerals and metals production practices, has welcomed both Weir and Agnico Eagle Mines as premium sponsors and early adopters of its Global Water Initiative.

Weir, a respected provider of engineered solutions to the resources sector, shares CEEC’s mission to drive the adoption of eco-efficient practices within the industry. Its renewed support as a premium sponsor underscores the company’s dedication to advancing sustainable minerals and metals production, according to CEEC.

The support from Agnico, a major gold producer, signifies a strategic alliance and collaboration aimed at promoting sustainable mineral processing and improved understanding of water management within the resources sector, CEEC said, with the association between the two companies grounded in a shared vision to accelerate the adoption of eco-efficient practices in the resources sector.

The Global Water Initiative, officially launching at the MetPlant 2023 Conference, being held on November 5-8 in Adelaide, Australia, is a critical step towards addressing water management and risk mitigation in the resources sector. The initiative seeks to build a shared understanding, identify gaps and outline necessary actions to ensure responsible water usage within the industry.

CEEC’s mission is to facilitate knowledge sharing, cross-sector collaboration and advocacy of eco-efficient practices within the global resources sector. By disseminating research findings, analytical tools and innovative solutions, CEEC aims to reduce energy and water consumption, as well as other associated impacts in mining, processing and refining of minerals, it says.

CEEC International says it encourages industry stakeholders to join the initiative, contribute to the discussions and collectively shape a more sustainable future for water management within the resources sector.

MotionMetrics-BeltMetrics

Weir eyes game-changing energy intensity reductions with ore characterisation project

With an extensive footprint from the rock face all the way through to tailings, it was only a matter of time before the Weir Group decided to enter the ore sorting game.

In recent years, the company has re-focused as a pureplay mining and aggregates company that can provide value throughout the flowsheet.

The company ditched its oil & gas exposure and added to its process plant and tailings remit with the acquisition of ESCO, a front-end-focused mining technology company with leading market share in the ground engaging tool (GET) segment.

Having more recently incorporated Motion Metrics into the mix – now within the ESCO division – it is embarking on a project that could have positive ramifications throughout the wider Weir Group offering.

Motion Metrics is a developer of artificial intelligence (AI) and 3D rugged machine vision technology. Its smart, rugged cameras monitor and provide data on equipment performance, faults, payloads and rock fragmentation (read: particle size distribution (PSD)). This data is then analysed using embedded and cloud-based AI to provide real-time feedback to the mining operation.

Initially developed for GET applications, these technologies have recently been extended into a suite of products and solutions that can be applied from drill and blast through to primary processing. Motion Metrics has, in the process, built up an impressive customer base and income stream, performing well since the acquisition.

Weir has outlined a £500 million-plus ($604 million-plus) emerging digital market opportunity for the entity, with much of this hinged on rugged machine vision technology, its sophisticated digital platform and the ability to add ore sensing to its offering.

This became clear at the company’s recent Capital Markets Day during a presentation from Chris Carpenter, VP of Technology for Weir ESCO.

Sensing, not sorting

At this event, Carpenter said the company was combining Motion Metrics’ PSD capability with ore characterisation technology to explore high-value opportunities for its clients.

“Looking further out, we believe ore characterisation…has the potential to transform mining by moving less rock, using less energy and creating less waste,” he said during his presentation. “Ore characterisation technology, which is underpinned by sophisticated sensing systems, captures critical data on properties and composition of rock, including rock hardness and mineral and moisture content.”

“When coupled with Motion Metrics fragmentation analysis technology, it has the potential to be a game changer, giving miners a full picture of the size and characteristics of rocks.”

Weir has outlined a £500 million-plus emerging digital market opportunity for Motion Metrics, with much of this hinged on rugged machine vision technology, its sophisticated digital platform and the ability to add ore sensing to its offering

This concept is not new. Measuring the quality of ore has been spoken of for decades and, more recently, has become a reality with the likes of MineSense, NextOre, IMA Engineering, Scantech, Malvern Panalytical and Rados International, among others, all having trialled technology or deployed commercial solutions across multiple commodities and sites.

Metso Outotec, one of Weir Minerals’ big competitors in the plant and tailings arena, has also spoken of the potential for bulk ore sorting by using its existing portfolio of material handling modules, crushing stations, mobile crushing equipment and bulk material handling solutions as the basis, while incorporating sensors from other vendors.

Weir believes it is one step ahead of its OEM counterpart in its pursuit of ore sorting, even if Carpenter is only referring to the trials currently being conducted at an unnamed copper mine as “ore characterisation” studies.

“With the acquisition of Motion Metrics, what we essentially bought was the ruggedised vision systems used in both mobile and fixed applications,” he told IM in January. “While the ore sensing piece is by no means trivial, the integrated AI capabilities and digital infrastructure that allows the data to be transported via a variety of avenues is incredibly important.

“Being able to pick up the data is one thing but being able to transport that data to the right people in a secure, accurate and timely manner is something different altogether.”

With a portfolio that includes LoaderMetrics™, BeltMetrics™, TruckMetrics™ and CrusherMetrics™, Motion Metrics and the Weir ESCO R&D team had several potential applications to start its ore characterisation journey with.

The company has settled on a BeltMetrics installation for its first trial, with Carpenter confirming the sensing solution under the microscope is currently positioned above a conveyor that is directly after the crusher in the flowsheet.

“We feel we will learn quickest over a conveyor belt, so it is really an expansion of the existing BeltMetrics solution that we will start with,” he said.

The sensing options open to Motion Metrics for this trial were also vast, with the aforementioned ore sorting vendors using the likes of X-ray Fluorescence, magnetic resonance, prompt gamma neutron activation analysis, pulsed fast thermal neutron activation, and others within their solutions.

Motion Metrics has chosen to incorporate hyperspectral imaging into its PSD mix.

Carpenter explained: “When you think about ore characterisation, we are just moving from a visual spectrum base with Motion Metrics vision-based systems to the expanded light spectrum for gathering data and making decisions. This is all being built on the established digital platform the company has.”

The company is not alone in using this type of technology. MineSense has spoken of trials using multispectral sensing technologies, while Australia-based Plotlogic has been tapping hyperspectral imaging to provide precision orebody knowledge prior to mining.

Collaborating on energy intensity reductions

Safety, scalability and flexibility were three factors taken into account with the hyperspectral imaging decision, but Carpenter was also aware of the potential limitations in using such technology.

Mines will need to be willing to make some changes and invest in alternative infrastructure to leverage the most value out of the solution the company is putting forward.

“That is where productivity partnerships that we spoke about on the Capital Markets Day are going to be really important,” he said. “It is going to be essential to collaborate with customers.”

The initial collaboration with the trial mine site looks to be extensive, stretching from the back end of December throughout 2023.

The site is already equipped with a significant amount of Weir Minerals and ESCO equipment, so the collaboration appears to have started well before this trial.

“Throughout the year, we will have the opportunity to make enhancements; starting out with an initial system that is upgraded,” Carpenter said. “By the end of the year, we should have high confidence of having something ready to commercialise. It could also be that we have other trials running concurrently with this one to extend the learnings.”

The two primary key performance indicators for the trial surround accuracy and speed, with Carpenter saying the company is targeting to at least meet the metrics competing technologies have been promoting over recent years.

“In both cases, we are well equipped to measure both and – in the initial phase – we are performing well,” Carpenter said.

“Right now, when they (the mine site) carry out an assay, they have to stop the conveyor belt, take a sample off and send it to a lab. At best, the feedback takes hours, if not days. Motion Metrics has done a really good job of building the sensors, algorithms and platforms to process the data coming from above that belt very quickly.”

There are a team of very experienced, PhD-equipped personnel currently working on this trial, monitoring the real-time results from Motion Metrics’ base in Vancouver, however there is a Weir network across the globe watching and waiting for news.

A sensor above a conveyor belt able to provide ore characterisation data is step one. Step two will most likely involve leveraging this data to provide insights as well as initiate downstream actions.

Then, there is the potential to equip these sensors for the pit on an excavator or wheel loader – which introduces many additional challenges both Motion Metrics and ESCO are aware of. Understanding exactly what is in the bank or going in the bucket will be critical to improving operational efficiencies.

These are longer-term goals that Motion Metrics, ESCO, Weir Minerals and Carpenter are cognisant of – and excited about – that may provide the true value to customers throughout the flowsheet.

“What is exciting for us is that – as may be obvious – the further upstream you can make some good decisions, the more energy you can save downstream,” he said. “As you get into some of the other processing elements in the plant, there are sustainability benefits to be had – a more efficient use of reagents to liberate the elements, a more efficient grinding setup based on ore characteristics, a reduction in water use, etc.

“The driver for this has really been sustainability and energy reduction. It is all about reducing the energy intensity associated with ore.

“We feel we are well equipped and in a good position to deliver on this and provide the industry with the step change in sustainability that it requires.”

Weir consolidates ESCO Eastern Canada footprint with Carriere Industrial Supply buy

The Weir Group says it has completed the acquisition of Carriere Industrial Supply Limited (CIS), a manufacturer and distributor of highly engineered wear parts and aftermarket service provider to Canada’s mining industry.

Its products, which include mining buckets and lip systems, help customers increase productivity through reduced downtime and improved safety, Weir says. The enterprise value for the transaction, which will see CIS join the ESCO Division, is £20 million ($26 million), subject to customary working capital and net debt adjustments.

The transaction builds on long relationship with CIS, acting as ESCO distributor in Eastern Canada for many years, Weir said, while delivering on ESCO’s strategy to have direct sales channels in major mining markets. It also increases ESCO’s capability in underground hard-rock mining applications, with CIS having a strong presence in gold and being located close to deposits of nickel and lithium.

According to Weir, the acquisition will be earnings- and margin-accretive in year one with returns expected to exceed the group’s cost of capital in the first full year of ownership.

Andrew Neilson, President of Weir’s ESCO Division, said: “The acquisition of CIS aligns with our strategy of providing direct sales and service to our mining customers and builds on our long-standing partnership, while also enhancing our capabilities in underground hard-rock mining applications.”

Weir to sell Oil & Gas division to Caterpillar

The Weir Group says it has entered into an agreement for the all-cash sale of its entire Oil & Gas division to Caterpillar Inc for an enterprise value of $405 million, subject to customary working capital and debt-like adjustments at closing.

This follows the announcement in February 2020 that Weir would seek to maximise value from its Oil & Gas division as it continued its strategic transformation into a premium mining technology pure play.

The agreement will see Weir generate net proceeds to reduce the group’s leverage, while the transaction facilitates a $70 million US cash tax benefit for Weir to be realised over the medium term, it said.

While the transaction is subject to Weir shareholder approval, the company is hoping for it be completed by the end of 2020, assuming normal regulatory clearances.

Selling the division to Cat will help Weir transition into a premium mining technology pure play “focused on attractive markets underpinned by global demographic trends, the transition to a low carbon society and adoption of new technologies in the mining industry”, it said.

It will also provide a “differentiated aftermarket, service and technology offering with proven earnings stability and strong cash generation through the cycle”.

The company’s strategic intent will now be to build on leading mission-critical positions in the mining supply chain from extraction to concentration and tailings management. It will be aided by a strengthened balance sheet to provide enhanced flexibility to invest in future growth opportunities, it said.

Jon Stanton, Weir Group Chief Executive Officer, said: “We are pleased to have reached this agreement that delivers a great home for the Oil & Gas division and maximises value for our stakeholders. Alongside the previous sale of the Flow Control division and the acquisition of ESCO, it is a major milestone in transforming the group into a focused, premium mining technology business.

“It means Weir is ideally positioned to benefit from long-term structural demographic trends and climate change actions, which will increase demand for essential metals that must also be produced more sustainably and efficiently. This will require the innovative engineering and close customer partnerships that define Weir, and it is why we are so excited about the future.”

Joe Creed, Vice President of Caterpillar’s Oil & Gas and Marine division, said: “Combining Weir Oil & Gas’s established pressure pumping and pressure control portfolio with Cat’s engines and transmissions enables us to create additional value for customers. This acquisition will expand our offerings to one of the broadest product lines in the well service industry.”

ESCO brings Nemisys lip system to hydraulic excavator market

ESCO says it is introducing the Nemisys N70 Lip System for hydraulic excavators as it looks to expand the tooth system’s reach beyond the large mining shovels, large excavators and wheel loaders it was initially developed for.

The Nemisys tooth system is a field-proven performer with installations on over 500 machines worldwide, ESCO, which was acquired by Weir in 2018, said. It helps reduce maintenance costs through improved reliability, faster and safer replacement, and improved lip coverage.

The N70 lip system features an integrated single-side lock for easier and faster removal to minimise machine downtime during maintenance cycles. The hammerless lock provides improved engagement with the nose to significantly reduce the chance of point loss and unplanned downtime. Adapters, meanwhile, feature a triple wear cap system to protect both legs.

The Nemisys N70 components are available to upgrade existing buckets to the premier ESCO system for exceptional performance and a lower cost of ownership over conventional lip systems, the company said.

ESCO is a leading designer, manufacturer and provider of highly engineered wear and replacement products and services essential to the performance of our customers’ equipment used in mining, construction and industrial applications.

Weir highlights Enduron HPGR and Terraflow tailings demand in H1 results

The Minerals and ESCO divisions continued to stand out in Weir Group’s half-year 2019 financial results, with the two mining focused segments now representing around 75% of group revenues.

The Weir Group recorded revenue of £1.3 billion ($1.6 billion) in the first six months of the year, up from £1.07 billion a year earlier prior to the ESCO acquisition. Operating profit, meanwhile, was £172 million, up 25% year-on-year, with the Minerals division posting an operating margin of 17.2% and ESCO recording a margin of 14.1% (up 300 basis points from a year earlier).

In addition to Minerals and ESCO now commanding some 75% of group revenues, the two’s recurring aftermarket sales also now represent about 80% of total revenues.

In the first half of 2019, Minerals orders grew 5% with aftermarket orders up 8%, reaching record levels, according to Weir. “Original equipment orders, which are traditionally lumpier, fell by 2% year-on-year, but returned to growth in Q2 (June quarter) and this is expected to accelerate in the second half,” the company said.

ESCO, meanwhile, recorded a 5% increase in pro-forma revenues to £280 million, with annualised cost savings of $20 million ahead of schedule when it comes to the company’s medium-term target of achieving $30 million synergies.

During the period, original equipment demand within the Minerals segment benefited from miners continuing to expand current operations and investment in new mines, with demand for new technologies that increase efficiency and sustainability while lowering total costs, Weir noted.

This included strong demand for the company’s Enduron® HPGR (high pressure grinding roll) technology that reduces water and energy consumption, the company said, adding that the company had been contracted to support a large greenfield development in the UK in the period.

Weir said it also saw growing interest in its Terraflow® solution to enable tailings waste to be cost-effectively recycled or repurposed. This equipment brings wet tailings down to 90% solids paste to be pumped into a containment area or used for paste backfill.

The company added: “Aftermarket demand was strong, due to production growth and structural trends. These include continued ore grade declines that increase the amount of rock that needs to be processed, intensifying wear and tear and leading to additional demand for spares and services,” the company added.

During the period, Weir also added a new Minerals service facility in Alaska, which, it said, gives the division the ability to rapidly respond to demand for spares and services and is a “key differentiator in need-it-now mining markets, where production intensity is increasing, and the costs of unplanned downtime are significant”.

The company’s technology work continued to focus on incremental innovations and “Mine of the Future developments” aimed at solutions that are smarter, more efficient and sustainable, Weir said. This included focusing research and development on new pump and alloy designs, digitisation, ore hoisting, hybrid separation and tailings management.

Weir ESCO benefited from the same macro mining trends as its Minerals segment including increased ore production and the focus by mining customers on optimising productivity, the company said.

“This supported demand for differentiated technology that is proven to sustainably increase efficiency,” it said.
The first half of the year saw early market share gains for the N70 Nemisys® lip system, which extends the division’s Nemisys technology – featuring a cast or plate lip with shrouds and a three-piece tooth system. This is currently being trialled on smaller machine classes including wheel loaders, Weir said. “The N70 improves customer productivity through increased wear life, lower fuel consumption and reduced maintenance costs.”

The company also launched its GET Detect System during the period, an innovation it worked with Australia’s Mining3 on that provides instant feedback to the machine operator if one of the ground engaging tools used to extract minerals is lost or damaged.

First Reserve becomes new owner of Weir’s Flow Control division

The Weir Group says it has completed the sale of its Flow Control division to First Reserve for an enterprise value of £275 million ($343 million).

The deal, which was first announced on February 25, completed on June 28, the company confirmed.

The Flow Control division primarily provides highly engineered pumps, valves and other solutions used in power, industrial and downstream oil and gas applications, according to Weir.

Back in February, the company said the sale would effectively strengthen its mining and oil & gas ties: “Once this transaction completes, on a pro forma basis, more than 80% of Weir’s revenues will be from attractive aftermarket-intensive mining and upstream oil and gas markets.”

Weir Group CEO, Jon Stanton, said: “The sale of the Flow Control division marks an important step in successfully delivering our strategy. It means Weir is now a more focused business with strong positions in premium upstream mining and oil and gas markets around the world.”

The £275 million enterprise value price is subject to customary working capital and debt-like adjustments, Weir clarified.

Demand for ground engaging tools leads Weir to invest in ESCO Newton plant

The Weir Group says it is investing an additional $15 million in its Newton manufacturing facility, in Mississippi, US, as part of a total $50-million plan to support an additional 150 jobs at the ESCO division plant.

When the investment programme is complete, employee numbers will be more than 400, a 60% increase from 2016, Weir Group said.

The Newton facility, one of Weir’s largest manufacturing operations, produces ground engaging tools for mining and infrastructure needs and was brought into the group with last year’s acquisition of ESCO. The expansion is slated to be complete by August 2019, Weir Group said.

Weir Group CEO, Jon Stanton, said: “The equipment we make in Mississippi is exported around the world and the increased demand from our mining and infrastructure customers gives us great confidence in the future.”

The Mississippi Development Authority (MDA) is providing assistance for workforce training, as well as statutory tax exemptions, according to Weir.

MDA Executive Director Glenn McCullough, Jr, said: “The Weir Group’s ESCO division with its talented employees show the world each day that global manufacturing leaders find the people and place needed for success in Mississippi. For nearly 50 years, ESCO’s workforce has enabled the company to achieve its goals by producing top-quality mining equipment used around the world, and this continued corporate investment demonstrates Weir’s commitment to doing business in our state.”

Approximately 80% of the products manufactured at the Newton facility are exported. This makes Weir’s ESCO division the world’s leading supplier of ground engaging tools for the mining industry, Weir said. The facility began operations in Newton in 1971.

Weir ESCO and Mining3 working on commercialising tramp metal detection system

Mining3 says an innovative tramp metal detection system – built into the bucket of mining equipment – is nearing commercialisation.

The company has been working on the new technology over the past few years subsequent to safety concerns and crusher damage caused by tramp metal such as bucket teeth, drill bits, tools and more, often remaining in mined material, it said. This can cause a loss of production and pose a significant safety threat to operators and maintainers.

Mining3 is working with Weir ESCO, an equipment metal parts manufacturer, for the incorporation of the uncrushables technology into its bucket design and will facilitate the commercialisation of the technology, Mining3 said.

“With the new patented uncrushables detection system, obstructive tramp metal can be identified and diverted before reaching the processing plant,” Mining3 said. “A pulse induction metal detector embedded inside the large steel bucket of a digging machine takes on the difficult task of detecting metal items scattered throughout the material. The system’s variable sensitivity is tuned for an object’s target size, focusing on larger, more obstructive uncrushables and allowing for the removal of smaller items further down the processing line. Further, the detection algorithm accommodates changes in ore grade and identifies the type of object.”

When metal is detected, the operator is alerted in real time, allowing for the necessary next steps – usually the dumping and diverting of the material, Mining3 said. In addition to the operator alert, the system integrates into a control centre interface and allows remote management and monitoring of the process.

The tramp metal detection approach requires minimal sensing equipment in the bucket and commercial versions will discreetly integrate the coil into the design, according to Mining3.

Successful site trials have led the project to integrate with larger and more technical machinery. Current prototypes are installed on Komatsu WA1200, Cat 992K, 993K and 994K machines operating on run-of-mine stockpiles in iron ore, gold and copper mines across the globe. Mining3’s research is now focused on deployability, robustness and optimisation, it said.
