Metso Outotec to deliver ‘multiple’ Vertimills to Ferrexpo’s Ukraine iron ore ops

Metso Outotec is to deliver multiple energy-efficient Vertimill® VTM-3000 stirred mills to Ferrexpo in Ukraine, with the vertical grinding mills set to become the largest of their kind to be installed in the country.

Once the mills have been installed, Ferrexpo’s iron ore beneficiation complex will be the largest VTM installation on the continent, Metso Outotec said, with several Vertimills already operating at the plant.

Typical values for this type of an order is in the range of €30-40 million ($35.7-47.6 million), depending on the scope of delivery, the company said. The order was booked in the company’s Minerals’ June quarter orders received.

Vertimill technology is part of Metso Outotec’s Planet Positive offering, providing the lowest total cost of ownership compared with other grinding mills in many applications thanks to its high energy efficiency, reduced media consumption, low installation cost as well as minimal liner wear and maintenance, the company claims. It is capable of handling feed sizes of up to 6 mm and grinding to product sizes of 30 microns or less. Vertimill is available in standard mill sizes ranging from 11 kW to 3,352 kW.

Ferrexpo has plans to increase output from its iron ore operations in Ukraine from 32 Mt/y to more than 80 Mt/y.

HYBRIT partners produce world’s first hydrogen-reduced sponge iron

SSAB, LKAB and Vattenfall say they have now produced the world’s first hydrogen-reduced sponge iron at a pilot scale.

The technological breakthrough in the HYBRIT initiative captures around 90% of emissions in conjunction with steelmaking and is a decisive step on the road to fossil-free steel, the partners say.

The feat from the HYBRIT pilot plant in Luleå, Sweden, showed it is possible to use fossil-free hydrogen gas to reduce iron ore instead of using coal and coke to remove the oxygen. Production has been continuous and of good quality, the companies said, with around 100 t made so far.

This is the first time ever that hydrogen made with fossil-free electricity has been used in the direct reduction of iron ore at a pilot scale, according to the HYBRIT partners. The goal, in principle, is to eliminate carbon dioxide emissions from the steelmaking process by using only fossil-free feedstock and fossil-free energy in all parts of the value chain.

Hydrogen-based reduction is a critical milestone, which paves the way for future fossil-free iron and steelmaking. SSAB, LKAB and Vattenfall intend, through HYBRIT, to create the most efficient value chain from the mine to steel, with the aim of being first to market, in 2026, with fossil-free steel at an industrial scale, they say.

Last year, HYBRIT, a joint initiative of SSAB, LKAB and Vattenfall, began test operations to make hydrogen-reduced sponge iron in the pilot plant built with support from the Swedish Energy Agency. The technology is being constantly developed and the sponge iron that has been successfully made using hydrogen technology is the feedstock for the fossil-free steel of the future, they say.

Jan Moström, President and CEO at LKAB, said: “This is a major breakthrough both for us and for the entire iron and steel industry. LKAB is the future supplier of sponge iron and this is a critical step in the right direction. Progress with HYBRIT enables us to maintain the pace in our transition and, already in 2026, we will begin the switch to industrial-scale production with the first demonstration plant in Gällivare, Sweden. Once LKAB has converted its entire production to sponge iron, we will enable the transition of the steel industry and reduce global emissions by around 35 Mt a year, which corresponds to two thirds of Sweden’s entire emissions. This is the greatest action we can take together for the good of the climate.”

Martin Lindqvist, President and CEO at SSAB, added: “This technological breakthrough is a critical step on the road to fossil-free steel. The potential cannot be underestimated. It means that we can reach climate goals in Sweden and Finland and contribute to reducing emissions across Europe. At the same time, it creates new jobs and export successes. SSAB’s transition means we will reduce carbon dioxide emissions by 10% in Sweden and 7% in Finland. High-strength fossil-free steel will also allow us to help our customers to strengthen their competitiveness. As early as this year, we will deliver minor quantities of steel made using hydrogen-based reduction to customers, and in 2026 we will deliver fossil-free steel at a large scale.”

The hydrogen used in the direct reduction process is generated by electrolysis of water with fossil-free electricity, and can be used immediately or stored for later use, according to the partners. In May, HYBRIT began work on building a pilot-scale hydrogen storage facility adjacent to the direct reduction pilot plant in Luleå.

Anna Borg, President and CEO at Vattenfall, said: “Sweden’s and Vattenfall’s fossil-free electricity is a basic requirement for the low carbon footprint of hydrogen-reduced sponge iron. The breakthrough that we can announce today shows in a very real way how electrification contributes to enabling a fossil-free life within a generation.”

NRW in line for A$702 million Karara Mining iron ore gig

NRW has received a letter of intent from Karara Mining Ltd to carry out mining services works at the Karara iron ore mine in the Gascoyne region of Western Australia.

Subject to reaching agreement with Karara, the anticipated value of the contract is around A$702 million ($529 million) over a five-year duration with a project workforce averaging circa-250 personnel.

MACA, through its recently acquired Mining West business, currently holds the contract mining agreement at Karara.

The works to be performed include load and haul, drill and blast, and run of mine re-handling. The drill and blast component will be undertaken by NRW’s wholly-owned subsidiary, Action Drill & Blast Pty Ltd. In addition, the work includes train loading and re-handling of the product stockpiles together with “miscellaneous day works” at the mine site, camp and access roads.

Karara is the largest mining operation and the first major magnetite mine in the Mid West region. It produces a premium, high-grade concentrate that it exports to steelmakers.

“With an expected mine life of 30-plus years, Karara’s operation includes a large open-pit mine, complex ore processing and beneficiation plant and significant infrastructure and logistics networks,” NRW said.

NRW estimates an equipment capital expenditure of around A$170 million to be progressively spent over the term, which will include the purchase of three 600 t face shovel excavators and a fleet of 220 t trucks.

NRW CEO, Jules Pemberton, said: “With a strong local presence in the area through our Geraldton-based DIAB Engineering business and our mining contract with Gascoyne Resources at the Dalgaranga mine site, we look forward to continuing to support the existing and highly experienced workforce on site through this transition, as well as creating employment opportunities for the Gascoyne region community.”

Karara CEO, Changjiang Zhu, said: “NRW is an established Western Australia-based mining and civil contractor with extensive open-cut mining experience gained through a number of successful mining operations in the state. Offering new prime equipment, NRW has the capability to undertake the entire Karara scope of work comprising a broad range of mining, construction and engineering services.

“We look forward to negotiation of an agreement with NRW and commencement of mining services early next year.”

Macarthur Minerals to explore use of LAVO hydrogen battery tech at Lake Giles

Macarthur Minerals Ltd has signed a strategic partnership and collaboration agreement with LAVO Hydrogen Technology Holding that could see the mine developer use LAVO’s hydrogen energy battery system on site at its flagship Lake Giles Iron project in the Yilgarn region of Western Australia.

The agreement will see the companies investigate the facilitation of a staged technology solution that is intended to deliver a clear carbon reduction strategy for Lake Giles, with a first phased roll-out to support Macarthur’s intended early hematite direct shipment ore (DSO) mining operations at Ularring.

LAVO uses an innovative, patented metal hydride to produce hydrogen energy batteries. The battery system acts as a solar sponge, integrating with solar arrays to capture and store renewable energy for use when needed. The unit creates hydrogen from water, stores the hydrogen into LAVO’s patented metal hydride and generates electricity by converting hydrogen into power, according to the companies.

LAVO’s cornerstone investors are ESG investment firm Providence Asset Group (PAG) and the University of New South Wales (UNSW). Together with UNSW, PAG established the Hydrogen Energy Research Centre (HERC). HERC is a leading university-industry partnership in hydrogen technologies with a main purpose of translating the university’s leading research in hydrogen production, storage and use into real world commercial products under the brand name ‘LAVO’.

Under the agreement, the first phase of collaboration is expected to involve Macarthur being assigned between three to five patented LAVO 40 kWh hydrogen storage units for integration into the remote worker accommodation facilities, which are planned to be constructed to support a DSO mining operation at Ularring.

Subject to successful project definition and satisfactory supporting economics being assessed, the LAVO hydrogen storage units could be installed on site at Ularring as early as the December quarter of this year.

If the trial program at Ularring is successful, then Macarthur and LAVO intend to examine opportunities to develop a fully localised micro-grid engineering solution that includes a solar photovoltaic array, a centralised hydrogen hydride containerised storage system and appropriately sized fuel cell to support the energy requirements for Macarthur’s planned high grade magnetite iron ore mine at Lake Giles, following successful delivery of the company’s current feasibility study. This could involve the integration of larger, containerised ‘HEOS’ hydrogen energy batteries with up to 13 MWh of capacity (currently being developed by LAVO), potentially delivering energy to Macarthur’s magnetite operations at a commercial scale.

Alan Yu, CEO of LAVO, said: “Macarthur Mineral’s pursuit to decarbonise mining and provide resources for green steel production is market leadership and an endeavour that LAVO is excited to be involved with. We are demonstrating our LAVO hydrogen hydride technology has practical, environmental and economically viable applications that extend from residential to significant mining projects.

“The potential for energy independence in the mining sector will reduce costly capital works and leverage the current transport gateways to drive profitable growth and improve environmental impacts.”

Andrew Bruton, CEO of Macarthur Minerals, said: “Macarthur is pleased to be partnering with LAVO on this ground-breaking initiative. Macarthur plans to roll-out integration of LAVO hydrogen storage units at Ularring to support intended early DSO hematite mining operations.

“This collaboration is also aimed at enabling Macarthur to achieve a clear carbon reduction strategy for its planned future magnetite operations at Moonshine, as it can allow for potential integration with magnetite processing on a modularised and gradual ‘scale up’ basis over a target five-to-10-year time horizon.”

He added: “By adopting this staged approach and becoming an ‘early follower’, rather than a ‘first adopter’, Macarthur will have the opportunity to contain technology, capital and pricing risk so as to ensure that it achieves the lowest possible levelised cost of energy delivery for its magnetite processing.”

LKAB to trial AI-backed XRF drill core logging with help of Minalyze and Sentian

LKAB, Minalyze AB and Sentian say they have joined forces in a consortium to develop the latest technology for scanning drill core.

In March 2020, LKAB started a test with the Minalyzer CS drill core scanner where the goal was to improve the workflow for core logging – ie how the results of exploration drilling are analysed. The test led to a permanent installation in Kiruna (Sweden) and expansion to Malmberget where data from the Minalyzer CS is used to help geological logging of the drill core.

The consortium of LKAB, Minalyze and Sentian are now set to take the use of data to the next level when boreholes in LKAB’s deposits are to be investigated. The new artificial intelligence application being developed by the trio will make the analysis much faster, with the time to evaluate a drill core reduced from weeks to minutes, with increased accuracy.

This could see Minalyze’s X-ray Fluorescence-backed CS scanner analyse LKAB drill core while leveraging Sentain’s industrial artificial intelligence solutions to make real-time decisions relating to drilling and exploration activities.

The technology development driven by the consortium will be a world first, changing the entire industry, the companies say.

Jan-Anders Perdahl, Specialist at LKAB’s Exploration Department, said: “With the collaboration, the core logging takes a big step through machine learning and artificial intelligence. The geologist can, at an early stage, place greater focus on the parts of the core that show chemical or other changes. Opportunities are opened up to gain increased knowledge about ore formation processes and alterations in a completely different way than before. One can also get indications that you are close to mineralisation and where it may be located, and thereby streamline exploration.”

The technological leap will give LKAB’s staff increased competence, increased quality in and efficiency of the work, as well as reduced need for other analysis methods, according to the companies.

Annelie Lundström, CEO of Minalyze AB, said: “We are at an interesting time when the hardware to extract consistently high-resolution data from drill cores is available and we can now take the next step and generate value from data together with our customers. In this collaboration, we will develop algorithms that can map rock layers in so-called lithological logs with very high confidence. This can only be done by combining expertise from all three parties.

“The results from our collaboration will forever change how drill core logging takes place everywhere and will result in a more efficient, non-subjective and consistent process.”

Martin Rugfelt, Sentian CEO, added: “We see great power in the application of modern artificial intelligence to data from the mining industry and there is major potential in further combining our machine learning technology with Minalyze’s unique capabilities in data collection and analysis.”

CSI to carry out load and haul, drill and blast work at Rio’s Brockman 2 iron ore mine

Mineral Resources Ltd’s CSI Mining Services has been awarded a mining contract by Rio Tinto to carry out work at the Brockman 2 iron ore mine in the Pilbara of Western Australia.

The scope of the contract will see CSI conduct load and haul, drill and blast, and short-term mine planning activities for Rio, the company said.

This will involve scheduling, drilling and blasting and then excavating 27 Mt of waste rock and iron ore over an approximate nine-month period, with a fleet of large-scale mining equipment, developing the Lens A/B pit for Rio.

This contract builds on a 16-year relationship with Rio, dating back to when CSI first commenced crushing services at the Nammuldi mine site. It also follows the completion of a 30 Mt load and haul contract at Rio’s Tom Price mine. CSI remains engaged at another Rio Tinto operation, Paraburdoo, where its team is carrying out 13 Mt of load and haul operations.

The Brockman 2 contract will generate around 150 jobs for CSI’s highly skilled workforce, the company said.

Mineral Resources’ Chief Executive Mining Services, Mike Grey, said: “We are delighted to have been invited by Rio Tinto to assist at another of its world-class iron ore mines. Our relationship with Rio Tinto dates back 16 years. Since then, we have been able to establish a track record of consistent project delivery for Rio Tinto, which we are very proud of.

“CSI is the world’s largest crushing contractor, so it is immensely satisfying that this latest Rio Tinto contract includes other mining activities, such as load and haul and drill and blast, to demonstrate CSI’s diverse skills set. We are confident this Brockman 2 scope of work will become the latest chapter of our ongoing association with Rio Tinto.”

Brockman 2 is one of the 16 mines that make up Rio’s world-class Pilbara iron ore operations.

The CSI team has begun mobilising to site, including delivering a new fleet of Komatsu 830E electric-drive dump trucks and a new Komatsu PC4000-11 excavator.

Ukraine iron ore miner cuts electricity consumption, process water use with DELKOR thickeners

As part of its modernisation drive, a mining and processing plant recently installed 3 x 62 m diameter DELKOR high-rate thickeners with a view to reducing electricity consumption by one and a half times for the pumping of tails, as well as rationalising the use of process water.

The project concerns the design, engineering and supply of three DELKOR 62 m high-rate thickeners for the dewatering of iron ore tailings as part of the processing plant’s modernised slurry thickening complex.

This modern complex, of which construction was completed in 2020, has now done away with outdated slurry pump stations, adopting, instead, the efficient process of thickening, hydraulic transport and storage of slurries.

Employing DELKOR’s latest generation feedwell design that comes with improved flocculation together with improved flocculant and slurry kinetics, these elevated thickeners boast large feedwells, which rank as some of the largest ever built, DELKOR says.

Ramesh Mahadevan, Regional Managing Director – DELKOR, had this to say upon successful commissioning of the thickeners: “This project is a very important reference for us in Ukraine. Given current global conditions, working with a new end user is a noteworthy achievement and one for which our entire DELKOR team must be commended.”

TAKRAF, the owner of DELKOR, meanwhile, says there has been strong demand for DELKOR technology in Latin America, noting a recent order for TAKRAF Peru for the supply of 2 x 38 m paste tailings thickeners with a capacity of 455-623 t/h.

The order, placed by a Peruvian entity processing tailings from a nearby iron ore mine, forms part of an expansion to develop a second plant. This will enable the entity to handle more tailings from the mine, according to TAKRAF.

Design requirements for the thickeners include accommodating the process demands for a paste application with a target of 65% +/- 3% solids content for the underflow. This required an equipment configuration that allowed it to operate under an expected yield stress of 200 Pa in the underflow material, the company noted.
