SIMPEC is to supply and install the electrical, instrumentation and communication works for the Solomon Central Facilities Workshop Yard at Fortescue Metals Group’s Solomon Hub iron ore operations in the Pilbara of Western Australia.

The contract, awarded by Central Systems, is valued at A$7 million ($5.4 million), according to SIMPEC, WestStar Industrial’s engineering contractor business. Work has commenced immediately.

FMG Solomon Pty Ltd, a subsidiary of Fortescue, is developing the Solomon Central Facilities Workshop Yard, which involves consolidating various workshops, facilities and other non-process infrastructure into a centralised location. Central Systems was awarded the A$57.5 million design and construct contract for the Central Facilities (picture courtesy of Central Systems) back in October, and SIMPEC will be working with the company on site to supply and install the electrical, instrumentation and communication works for these facilities.

This award, SIMPEC’s first from Central Systems, builds on the portfolio of non-process infrastructure work packages successfully undertaken by SIMPEC across Western Australia and Sydney, New South Wales, the company said.

SIMPEC Managing Director, Mark Dimasi, noted: “To be part of this new development in the non-process infrastructure space on a Fortescue Metals Group project is very rewarding for the team. This large project allows SIMPEC to showcase its true electrical and instrumentation capabilities.”

Fortescue’s Solomon Hub is in the Hamersley Ranges and comprises the Firetail and Kings Valley mines, which together have a production capacity of 75 Mt/y. At the hub, higher iron grade, low cost Firetail ore is blended with low phosphorous Chichester ore to create the company’s Fortescue Blend.

First Graphene predicts increased PureGRAPH wear line lifespan following Pilbara trial

Mining consumables, Mining equipment, Mining services, Steel and iron ore, , , , , , , ,

First Graphene says results from field testing of a PureGRAPH®-enhanced bucket wear liner have shown an almost six times reduction in average abrasion loss compared with a standard polyurethane liner.

Rubber wear liners are an essential component on steel fabricated mining equipment, providing a resilient, sacrificial layer to protect the steel equipment from abrasion wear during ore handling operations. The wear liners are replaced periodically and extending the periods between replacement helps maximise throughput at the mine.

The bucket wear liners were installed at a major iron ore producer’s load-out facility in the Pilbara of Western Australia, beginning in mid-2019. A standard wear liner and a graphene-enhanced ArmourGRAPH™ wear liner ran simultaneously in the same location for the 62-week period.

The ArmourGRAPH liners, developed by First Graphene and its partner newGen Group, had been prepared using a low addition rate of PureGRAPH 20 in hot cast polyurethane (PU). The PureGRAPH enhanced liners were used side-by-side with standard PU liners throughout the 62-week trial before being returned to newGen Group for assessment.

A detailed abrasion analysis confirmed the abrasion loss was significantly reduced in the PureGRAPH-enhanced ArmourGRAPH liner, with a circa-6 times reduction in average abrasion loss (improved resistance to wear). As abrasion loss is the primary mechanism of failure, a significant 6 times increase in lifespan of the wear liner is anticipated, First Graphene said.

The abrasion analysis was performed on the rear sliding face of the bucket liner as this surface is well fitted to the steel bucket and provides the most representative analysis of liner wear life, according to the company.

First Graphene CEO, Mike Bell, said the results indicated the benefits and value PureGRAPH could provide to mining and mineral processing operators.

“Reducing production downtime is major area of focus in mining and these results show the significant improvements that can be gained from adding small amounts of PureGRAPH to polymer formulations,” Bell said.

newGen Group Managing Director, Ben Walker, added: “The results of this extended trial prove that our ArmourGRAPH liners can deliver vast improvements for operators. We anticipate strong demand for a broad range of graphene-enhanced consumable products across the mining and mineral processing sectors.”

BHP has signed a memorandum of understanding (MoU) with China’s HBIS Group Co Ltd, one of the world’s largest steelmakers and a major customer of BHP’s iron ore, with the intention of investing up to $15 million over three years to jointly study and explore greenhouse gas emission reduction technologies and pathways.

Under the partnership, BHP and HBIS Group intend to collaborate on three priority areas: hydrogen-based direct reduction technology, the recycling and reuse of steelmaking slag, and the role of iron ore lump use to help reduce emissions from ironmaking and steelmaking.

The partnership aims to help both companies progress toward their climate change goals and support the steel industry’s role in helping to achieve China’s ambitions to be carbon neutral by 2060.

BHP’s Chief Commercial Officer, Vandita Pant, said: “We view decarbonisation of the steel industry as a complex puzzle that requires multiple technological solutions across the value chain over different time horizons. By forming this third low-carbon steelmaking partnership with HBIS Group, we are focusing on additional components, such as the role our products play in hydrogen-based steel production, that complement our other partnerships and support for endeavours in emissions reduction and capture from the traditional blast furnace route.”

In February, the mining major signed a similar MoU with leading Japanese steel producer, JFE Steel, while, in November 2020, BHP and China Baowu signed a pact that could see up to $35 million invested in tackling greenhouse gas emission reductions in the global steel industry.

BHP’s investment would be drawn from its $400 million Climate Investment Program, established in 2019 to support projects, partnerships, research and development to help reduce Scope 1, 2 and 3 emissions.

BHP Chief Executive Officer, Mike Henry, said: “BHP has a long and trusted relationship with HBIS Group, and we are pleased to establish this strategic partnership to explore new ways to reduce emissions from steelmaking. Global decarbonisation will require collaboration and collective effort, and our work with partners such as HBIS Group will build on our own actions and help reduce emissions right through the value chain.”

Chairman of the World Steel Association, Party Secretary and Chairman of HBIS Group, Yu Yong, said: “The signing of the MoU fully demonstrates the two companies’ commitment to creating a green and low-carbon future across the value chain and a shared sense of responsibility to address climate change together, with a common vision to ‘contributing to a community of a shared future for mankind’. This partnership ushers in a new chapter for the two companies to deepen our strategic cooperation and to achieve collaborative development.”

BHP has also been active in other areas to reduce emissions, including awarding the world’s first LNG-fuelled Newcastlemax bulk carrier tender and the first LNG supply agreement for those vessels, and renewable energy supply contracts for BHP’s Queensland coal mines and Nickel West operations.

Atlas Iron has hauled its first shipment of ore by road to Port Hedland, in Western Australia, from its new Sanjiv Ridge operation in four brand new pink trucks.

After announcing the first ore crushed earlier this month, the Hancock Prospecting owned company reached this new milestone this week.

Some 4-5 Mt/y of iron ore lump and fines is to be hauled by road to the Utah Point stockyard, which will add 5-6 years to the Atlas value chain, the company says. It comes with 64 Mt at 57.2% Fe of mineral resources and 29 Mt at 57% Fe reserves.

Sanjiv Manchanda, Atlas Iron CEO, said: “I’m so proud of our team of Atlas staff and our contracting partners, MGM Bulk, MACA and CSI for working so tirelessly to ensure we surpassed our project targets. It’s always a team effort, and our small team certainly knows how to get things done safely, efficiently and with agility to get a win-win outcome.

“I also take this opportunity to thank our partners MGM Bulk and CSI Mining (a Mineral Resources Ltd subsidiary) who painted their four brand new trucks and crusher, which were used today and for the duration of the project, a striking pink colour in recognition of our Group and Executive Chairman’s commitment to supporting breast cancer research and improving patient care. These pink trucks now add to a large amount of mining infrastructure in the Pilbara now pink, including trains, ships, processing plants, crushers and mining trucks.”

Mineral Resources Ltd’s CSI Mining Services team has reached a major milestone with the NextGen II modular crushing plant having now crushed its first ore at the BHP-owned Mt Whaleback iron ore mine in the Pilbara of Western Australia.

The relocatable plant, developed by CSI and Metso Outotec, has been painted in Lifeline WA’s trademark blue and displays the 13 11 14 crisis support number.

The crusher has been on a monumental journey to get to its final home in the Pilbara, transported by a sea vessel from its manufacturing site in Turkey to CSI’s Kwinana workshop.

“The CSI team at Kwinana worked around the clock to assemble the revolutionary relocatable modular design last year, which allows for sustained reliable performance over time with the flexibility required to meet our clients’ changing and challenging production demands,” the company said.

CSI was awarded the contract to design, construct and operate the 12 Mt/y crushing plant back in June. It was due to replace the existing CSI crushing plant at the iron ore operation.

The crushing and screening plant is expected to come with low capital and operating costs, in addition to significant flexibility with its portability. It is assembled in modules and, compared with fixed crushing plants, provides for sustained reliable performance over time with the flexibility required to meet clients’ changing and challenging production demands, according to CSI.

LKAB welcomes more autonomous LHDs at Kiruna ahead of electric machine arrivals

LKAB says it is now running six autonomous LHDs at its Kiruna iron ore mine, in northern Sweden, with battery-powered and cable-electric machines set to arrive at the operation later in the year.

The company has been stepping up its automation efforts at the underground mine, going from three autonomous loaders in November to five in December and, now, six as of this month.

These loaders have come from both Sandvik and Epiroc, with at least three of these being 21 t Sandvik LH621i LHDs and two being 18 t Epiroc Scooptram ST18 LHDs.

“For the time being, the loaders are diesel-powered, but battery-powered Epiroc machines and Sandvik’s larger electric loaders will be delivered this year,” the company said. “Safety and loading capacity will be tested and assessed, so that the vision of a carbon-dioxide-free LKAB can be realised.”

Magnus Lindgren, Production Manager for the remote-control centre at level 1365 in the Kiruna mine, said: “Our operators work in close collaboration with both Sandvik and Epiroc and, thereby, take part in these suppliers’ development. We test the systems and provide feedback, so we can eventually take delivery of a better product.”

LKAB conducts blasting at the mine each night. When the blasting gases have been evacuated and rock stresses have decreased, personnel can access the production area. With remote-control machines, LKAB can load, haul and dump crude ore without having to worry as much about these considerations.

Roger Lärkmo, Engineering Developer at LKAB, added: “Autonomous loading at night is optimal in terms of both safety and work environment, and from a productivity perspective. That doesn’t mean manually-operated machines are a thing of the past; it just means that we have more tools in the toolbox. Many parameters have to be taken into the equation for our loading operations to deliver an even flow of ore to the processing plants.”

This summer, the Konsuln mine will take delivery of its first battery-powered loader, the 14 t ST14 from Epiroc. Epiroc said last month it will also deliver a Minetruck MT42 Battery for use at the main Kiruna iron ore mine for production, and in the Konsuln test mine.

Preparations are now under way for the ST14 Battery’s arrival at Konsuln, from planning of the drifts where batteries will be exchanged, to risk analyses and simulations, LKAB said.

During 2021, three of Sandvik’s larger 625IE electric loaders, which have a 25-t payload capacity, will also be delivered to LKAB in Kiruna. The company took delivery of a “renewed” Sandvik LH625iE electric loader for field testing in 2020.

Lindgren said: “LKAB has been running loaders with electric power cables for more than 20 years, both manually operated and with remote control. Now we are going to test the new generation of electric loaders. These tests will begin in the autumn.”

Anita Oraha Wardi, Project Manager for autonomous, smart and carbon-dioxide-free machines at LKAB, said the company was participating in development work early on, so it can understand and influence performance, loading capacity and, not least, the safety aspects.

“We are going to test to see how battery-driven and electric loaders compare with diesel-powered machines, and how remote-control machines function in comparison with manually-operated loaders,” she said.

“One of several objectives is that operators, regardless of the make or model of the vehicle, should be able to run remote-control vehicles via the same system and in the same production area. Then, we will be approaching a world standard.”

thyssenkrupp rail-mounted stacker handed over to BHP South Flank

thyssenkrupp says it has handed over the world’s largest rail-mounted stacker to its client BHP for the South Flank iron ore development in Western Australia,

The first stacker among a “trio of giants”, ST-04 took more than three years of research and design development in six countries, and two years of significant local fabrication, construction and commissioning processes, thyssenkrupp said.

Over the next few months, it will gradually ramp up its operating capacity of 20,000 t/h.

The engineering company was awarded this contract − one of its largest ever fabrication and construction projects in Western Australia − by BHP back in late 2018.

Under the €150 million ($181 million) contract, thyssenkrupp was to supply two stackers that deposit iron ore into stockyards for loading, and a reclaimer for loading the ore onto trains for transport to Port Hedland. The machines’ capacity of 20,000 t/h made them the largest rail-mounted stackers and reclaimers in the world, according to the company.

Primero has been helping thyssenkrupp in this pursuit, carrying out pre-assembly of the machines at its Australian Marine Complex, in Henderson, Western Australia.

In BHP’s half year results to December 31 released earlier this week, it said South Flank remained on budget and on track to deliver first production by mid-2021. The company expects the operation to ramp up to 80 Mt/y of output, helping replace production from the existing Yandi mine, which is reaching the end of its economic life.

SRG Global Managing Director, David Macgeorge, said: “We are delighted to be selected as a key partner to FMG and to provide critical maintenance and shutdown services across their Pilbara operations for the next five years. This is another significant step forward in our strategy to build a portfolio of annuity earnings, with quality clients, to deliver long-term sustainable growth.”

Kobe Steel demonstrates new, cleaner steel production technology

Kobe Steel says it has successfully demonstrated technology that can significantly reduce CO2 emissions from blast furnace operations, combining the technologies of Midrex in the engineering business and the blast furnace operation technology in the iron and steel business.

This achievement is a result of the integrated efforts of the Kobe Steel Group (also known as the KOBELCO Group) leveraging its diverse businesses, it said. The demonstration test was conducted for a month at a large blast furnace (4,844 cu.m) of the Kakogawa Works in Hyogo Prefecture, Japan, in October 2020.

The quantity of CO2 emissions from the blast furnace is determined by the reducing agent rate (RAR), or the quantity of carbon fuel used in blast furnace ironmaking. In the demonstration test, it was verified that RAR could be stably reduced from 518 kg per tonne of hot metal (thm) to 415 kg/thm by charging a large amount of hot briquetted iron produced by the MIDREX® Process. The results indicate that this technology can reduce CO2 emissions by approximately 20% compared with the conventional method, the company said.

In addition, the world’s lowest level of coke rate (239 kg/thm) has been achieved in the demonstration test of this technology, the company claimed.

Kobe Steel sees this as a promising solution that could become readily available soon at a lower additional cost compared with other CO2-reduction measures.

The MIDREX Process uses natural gas as the reductant and pellets made of iron ore as the source of iron to make direct reduced iron through the reduction process in the shaft furnace. In comparison with the blast furnace method, the MIDREX Process can reduce CO2 emissions by 20-40%.

The company said: “We will keep improving this CO2-reduction solution technology while further reducing CO2 emissions and achieving lower costs for CO2 reduction. Beyond our own efforts to reduce emissions from our facilities, we will strive to contribute to the acceleration of CO2 reduction through introducing this solution to blast furnaces around the world.

“In addition, we believe that the success of the demonstration test on an actual blast furnace has made a significant step forward in providing low CO2 steel products to customers. As moving forward with our environmental efforts on the scale of the whole supply chain, we will establish production and sales systems and define the terms and conditions for sales so that we can provide customers with low CO2 steel products that offer new added value.”

Primero completes WHIMS project at Fortescue’s Christmas Creek iron ore op

Primero Group says it has completed the construction of a Wet High Intensity Magnetic Separation (WHIMS) processing plant at Fortescue Metals Group’s Christmas Creek iron ore mine in Western Australia.

The plant is expected to improve product grade and mass recovery from the desands unit at the Christmas Creek Ore Process Facility #2.

The flowsheet is based on a simple and robust configuration, where wet screen undersize at a nominal -1 mm is treated in open circuit through a low intensity magnetic stage, followed by a vertical WHIMS stage to produce a concentrate stream and a tailings stream, which can be integrated with the existing process and auxiliary equipment. The vertical WHIMS project entails the redirection of the wet screen undersize stream from the existing scrubbing circuit to feed the brownfield magnetic separation plant.

“We can proudly say that despite the impacts of COVID-19 and the fast-tracked nature of the project, the plant was successfully delivered and commissioned in less than 12 months – meeting all safety and project key performance indicators,” the company said.

Primero put the project’s success down partly to the “enhanced opportunity for collaboration early contractor involvement (ECI) provides”.

It added: “A flexible approach to project development that ensures the needs of all project stakeholders can be met prior to detailed design and implementation in a lump sum engineering procurement and construction (EPC) environment. This constructive, relationship-based contracting continued throughout construction, commissioning and now operation – demonstrating the power of the ECI contracting model when coupled with Primero’s unique, vertically integrated EPC capability.”
