Antofagasta’s automation and electrification journey bearing fruit

Antofagasta’s purpose of ‘Developing Mining for a Better Future’ has seen the Chile-based copper producer lead from the front in terms of the adoption of both automation and electrification.

The company launched a digital roadmap all the way back in 2017, which, over the following years, has seen it advance projects to automate blasthole drills and haulage trucks, leverage remote operation centres and integrate advanced data analytics into its decision-making process.

Backed by a digitally-literate talent pool and underwritten by a series of roadmap and plans, Antofagasta is setting itself up for the long term.

When it comes to electrification, the company has played a key role in furthering research on the use of hydrogen fuel cells in haulage applications on mine site conditions. It has also signed up as a patron in the Charge On Innovation Challenge, being one of 19 companies looking to accelerate commercialisation of interoperable solutions that can safely deliver electricity to large battery-electric off-road haul trucks.

Outside of consortium projects, it has announced plans to also study and test the development of battery-powered trucks at its Antucoya operation and has outlined plans for a trolley assist pilot project at the Los Pelambres copper mine in Chile.

And, in April 2022, the company reached the goal of all its mines operating on fully renewable power.

Alan Muchnik, VP Strategy & Innovation for Antofagasta, says all of these developments epitomise the company’s overarching aims.

“The objective we have is to develop the next generation of mining practices to enable growth and reduce our company’s environmental footprint,” he told IM.

In addition to the digital roadmap the company outlined five years ago, Antofagasta has been carrying out all its electrification projects under the guise of an Electromobility Plan – part of its wider climate change strategy.

Following the achievement of its previous emissions reduction target of cutting both its Scope 1 and Scope 2 carbon dioxide emissions by 300,000 tonnes of CO2e between 2018 and 2022 – a goal it achieved two years early – the company set a more ambitious target in 2021. This is looking to achieve carbon neutrality by 2050 – in line with Chile’s national commitment – and reduce emissions by 30% by 2025, relative to 2020 performance. One element of the company’s efforts to reduce emissions has, as mentioned, seen its operations run solely from renewable energy as of April this year.

According to Antofagasta’s own calculations, in 2020, two-thirds of its greenhouse gas emissions from diesel combustion were attributable to its mine haulage trucks.

“In this respect, Antofagasta is actively participating in initiatives that seek to replace the diesel used by mining haulage trucks,” Muchnik said.

“As part of that electromobility roadmap, we have considered our participation in early-adoption projects with a view to pilot and scale promising technologies.”

With the HYDRA Consortium – which includes Antofagasta, ENGIE, Mining3, CSIRO Chile, Liebherr and Mitsui & Co – specifically, the company has been one of the driving forces of hydrogen haulage adoption on mine site conditions.

It has confirmed that it will test a fuel cell and battery powertrain propulsion system at its Centinela mine, with the first HYDRA prototype expected to start functional testing shortly. This will allow Antofagasta to assess the powertrain’s behaviour and performance under real mine conditions, including at high altitude with suspended dust. It will also help establish technical and safety protocols for hydrogen use at scale in mining, which will be vital for the fuel’s successful deployment across the industry.

The trolley assist project at Los Pelambres under study, meanwhile, consists of implementing a trolley system on, first, uphill ramps. This will consist of one lane of a two-lane ramp, which will allow for trucks coming behind to leave the trolley and overtake a stopped truck still on the line.

“Some of these projects may bring an early opportunity to transform specific sites as we transition towards the longer-term prevailing solution to implement at our sites and help reduce our Scope 1 footprint,” Muchnik said.

“Each mine has their unique characteristics and different technologies may become more attractive depending on those characteristics or may become complementary in enabling that diesel replacement.”

Of course, automating the haulage and blasthole drilling processes will help the company reduce its Scope 1 emissions through more efficient operations. It will also help offset some of the higher costs of inputs and inflation that come with operating in Chile.

Similarly, all of Antofagasta’s sites have strong data analytics teams to identify opportunities for efficiency gains and continuous improvement.

Reflecting on the gradual rollout of automation across the company’s operations, Muchnik referred to the overarching roadmap the company outlined in 2017.

“This roadmap considered different strategic programs with rollout options that improve productivity and safety, with automation being a relevant dimension,” he said. “It was built on the concept of knowledge transfer to enable other companies of the group to benefit and learn from the experiences at specific sites.”

That has worked from the looks of it, going from Epiroc Pit Viper autonomous drill deployments at Los Pelambres to the rollout of the technology at Esperanza Sur (part of Centinela).

A fleet of 11 autonomous electric drive Komatsu 980E-5 trucks have also gone live at Esperanza Sur over this time frame.

“Another good part of that is the Integrated Remote Operating Centres (IROC) we have setup to support these operations,” Muchnik said. “We recently opened an IROC for Centinela in the city of Antofagasta and, following the same transfer process, Los Pelambres is expected to go live with their IROC here in Santiago, in the second half of 2022.”

Muchnik says one of the many benefits of the IROCs is the ability to attract and retain talent for Antofagasta’s operations.

“It is not just about bringing in new talent but working with our people to be allow them to move with this transformation and become digitally literate to help us prepare for an autonomous and remotely-operated future,” he said.

An in-house digital academy that Muchnik and his colleagues launched in 2020 has been vital in this process.

“It has enabled a different mindset within our workforce, preparing them for the transition through training and learning.

“This has ensured all of our employees go through the journey with us.”

Anglo American commences first longwall shear at Aquila met coal mine

Anglo American’s new Aquila mine has achieved its first longwall shear of steelmaking metallurgical coal on schedule and on budget, marking the project’s final stages of construction and commissioning, it says.

The Aquila mine, located near Middlemount in Central Queensland in Australia, extends the life of Anglo American’s existing Capcoal underground operations by seven years, after the company’s nearby Grasstree mine reached its end of life in recent weeks.

Themba Mkhwanazi, CEO of Bulk Commodities, said: “We have delivered the Aquila project on time and within our budgeted attributable cost of $226 million. This new mine will have a total average annual saleable production of around five million tonnes of premium quality hard coking coal and benefits from low capital intensity as we are using the existing infrastructure and systems from our adjacent operations. Aquila offers us highly attractive returns and margins at conservative long term consensus prices.”

Tyler Mitchelson, CEO of Anglo American’s Metallurgical Coal business, said: “Safely starting up longwall mining at Aquila Mine on our original schedule, despite the effects of the pandemic, is an important milestone for our Metallurgical Coal business and will support our ongoing contribution to both the Middlemount community, and Queensland’s economy. The mine uses our existing infrastructure at our Capcoal complex and supports around 600 ongoing operational roles for our Queensland-based workforce, including providing continuity of employment for our Grasstree mining team.”

The Aquila Mine has been developed as one of Australia’s most technologically advanced underground mines, leveraging Anglo American’s advancements in underground automation technology, remote operations and data analytics, the company says. The mine features two longwalls, allowing operations to continue without the downtime usually required for longwall moves. Both longwalls are fully remote-capable and will be sequentially operated from a site-based remote operations centre on the surface of the mine.

Anglo American’s Capcoal complex comprises Capcoal Open Cut Mine, Grasstree Mine, Aquila Mine, the Coal Handling and Preparation Plant and associated infrastructure. Aquila is owned 70% by Anglo American and 30% by Mitsui & Co. Ltd.

Water treatment plant starts up at Anglo American’s Aquila met coal project

Anglo American’s Metallurgical Coal business says it is now operating the first of two state-of-the art reverse osmosis (RO) water treatment plants at its Aquila project in the Bowen Basin, Queensland.

The aim of the RO plants is to reduce the use of fresh water in its mining operations.

Chief Executive Officer of Anglo American’s Metallurgical Coal business, Tyler Mitchelson, said the A$5 million ($3.9 million) water treatment system was currently treating two megalitres of mine affected water (MAW) a day and supporting construction of the Aquila Mine, near Middlemount in central Queensland.

“A key target in Anglo American’s global Sustainable Mining Plan is to reduce our reliance on fresh water by 50% by 2030 across our mine sites, and I’m pleased to say Aquila is currently sourcing recycled water during construction of the mine,” Mitchelson said.

“A planned second RO plant will to be used to recycle a further 2.4 megalitres of MAW – once Aquila becomes operational in early 2022, more than doubling capacity and helping to reduce the reliance on water from local sources during times of drought.

“Aquila will be one of the world’s most technologically advanced underground mines and will showcase our innovation-led approach to sustainable mining. The project is currently supporting 500 jobs.”

Aquila, owned 70% by Anglo and 30% by Mitsui & Co Ltd, will extend the life of Anglo’s existing Capcoal underground operations by six years and continue to use the associated infrastructure at the Capcoal complex as its nearby Grasstree Mine approaches end of life, Anglo says. The mine will also continue to adopt Anglo American’s FutureSmart Mining™ program, which applies innovative thinking and technological advances to address mining’s major operational and sustainability challenges, the company said. One of the initiatives the company is working on as part of this is remote operation of the longwall; a process the company has trialled at some of its other Bowen Basin coal mines.

Aquila’s Project Director, Tony Willmott, said the A$240 million Aquila Mine was committed to awarding contracts locally.

“Our Aquila project is progressing well, with support from its Queensland-based workforce and contracting partners. More than 90% of our Aquila contracts have been awarded to Queensland-based suppliers,” Willmott said. “Aquila’s integrated network of pipes and pumps is securing the distribution of high-quality water which is necessary in metallurgical coal mining for equipment cooling and coal cutting operations.”

Vale, Kobe Steel and Mitsui & Co to combine ‘green’ iron-making solutions

Vale says it has reached a non-binding heads of agreement with Kobe Steel and Mitsui & Co to establish a new venture to supply low CO2 iron metallics and iron-making solutions to the steel industry.

The heads of agreement establishes the preliminary terms and conditions for the creation of a new venture with the objective of delivering low CO2 metallics to the global market, providing new technological solutions to its clients, Vale said.

“An evaluation period has already begun to deepen the cooperation and to gauge market demand for several existing and new steel-making solutions prior to a final agreement for the creation of the NewVen,” it added.

Vale has previously declared 2030 targets for Scope 1 and 2 emissions in line with a commitment to the Paris Agreement.

Steel production, part of Vale’s Scope 3 emissions, while essential for people’s daily lives, generates considerable CO2 emissions. “Vale is committed to contribute with its steel-making clients in this challenge of reducing their carbon footprint,” it said.

The new venture will use existing and new low-CO2 iron making technology such as Tecnored®️ technology and the MIDREX®️ Process.

Tecnored is a 100%-owned Vale subsidiary focused on developing a low carbon pig iron process through the use of energy sources, such as biomass, syn-gas and hydrogen, that emits less CO2 than the traditional coal and coke iron-making process. Using biomass, the path to economic carbon neutrality may be achieved in the medium term, according to Vale.

MIDREX Technologies, a 100%-owned Kobe Steel subsidiary, is a world leading direct reduction ironmaking (DRI) technology. Each year, MIDREX plants produce more than 60% of the entire world’s DRI (example above) and more than 80% of the DRI produced by all shaft furnace technologies. Since it uses both natural gas and hydrogen as a reductant in the process, its CO2 emission level is much less than compared with a blast furnace.
