Anglo American Platinum’s modernisation drive to continue into 2021

Anglo American Platinum says it is looking to deliver the next phase of value to its stakeholders after reporting record EBITDA for 2020 in the face of COVID-19-related disruption.

The miner, majority-owned by Anglo American, saw production drop 14% year-on-year in 2020 to 3.8 Moz (on a 100% basis) due to COVID-related stoppages. Despite this, a higher basket price for its platinum group metals saw EBITDA jump 39% to R41.6 billion ($2.8 billion) for the year.

As all its mines are now back to their full operating rates, the company was confident enough to state PGM metal in concentrate production should rise to 4.2-4.6 Moz in 2021.

Part of its pledge to deliver more value to stakeholders was related to turning 100% of its operations into fully modernised and mechanised mines by 2030. At the end of 2020, the company said 88% of its mines could be classified as fully modernised and mechanised.

There were some operational bright spots during 2020 the company flagged.

At Mogalakwena – very much the company’s flagship operation – Anglo Platinum said the South Africa mine continued its journey to deliver best-in-class performance through its P101 program.

Rope-shovel performance improved to 26 Mt in 2020, from 15 Mt in 2019, while drill penetration rates for big rigs increased from 15 m/h, to 16.7 m/h. Alongside this, the company said its Komatsu 930E truck fleet performance improved to 298 t/load in 2020, from 292 t/load in 2019.

These were contributing factors to concentrator recoveries increasing by two percentage points in 2020 over 2019.

During the next few years, the company has big plans to further improve Mogalakwena’s performance.

In 2020, the mine invested R500 million in operating and capital expenditure, which included commissioning a full-scale bulk ore sorting plant, coarse particle rejection project and development of the hydrogen-powered fuel-cell mining haul-truck (otherwise referred to as the FCEV haul truck).

First motion of the 291 t FCEV haul truck is still on track for the second half of 2021, with the company planning to roll out circa-40 such trucks from 2024.

Anglo Platinum said the bulk sorting plant (which includes a Prompt Gamma Neutron Activation Analysis and XRF sensor-based setup, pictured) campaign at the Mogalakwena operation is due to end this quarter.

The company’s hydraulic dry stacking project is only just getting started.

This project, which involves coarse gangue rejection before primary flotation for safer tailings storage facilities, is expected to see a construction start in the June quarter, followed by a campaign commencement and conclusion in the September quarter and December quarters, respectively.

On another of Anglo Platinum’s big technology breakthrough projects – coarse particle rejection for post primary milling rejection of coarse gangue before primary flotation – the company plans to start a campaign in the December quarter of this year and conclude said campaign by the end of the March quarter of 2022.

The company also has eyes on making progress underground at Mogalakwena, with a hard-rock cutting project to “increase stoping productivity and safety” set for Phase A early access works this year. This project is set to involve swarm robotics for autonomous, 24/7 self-learning underground mining, the company said.

Lastly, the company’s said the digital operational planning part of its VOXEL digital platform had gone live at Mogalakwena. VOXEL is expected to eventually connect assets, processes, and people in a new digital thread across the value chain to create a family of digital twins of the entire mining environment, the company says. Development is currently ongoing.

Looking back to 2020 performance at the Unki mine, in Zimbabwe, Anglo reflected on some more technology initiatives related to R26 million of expenditure for a digitalisation program. This included installing underground Wi-Fi infrastructure, as well as a fleet data management system to track analytics on primary production equipment. The company says these digital developments will enhance real-time data analysis, improve short-interval control and overall equipment effectiveness.

To step up mechanisation of its PGM operations at Amandelbult, Anglo American Platinum is also investing in innovation.

This includes in-stope safety technologies such as split panel layouts to allow buffer times between cycles, creating safer continuous operation and reduced employee exposure; improved roof support technology and new drilling technologies; a shift to emulsion blasting from throw blasting; and safety enhancements through fall of ground indicators, 2 t safety nets, LED lights, and winch proximity detection.

Meanwhile, at the company’s Mototolo/Der Brochen operations, it is working on developing the first lined tailings storage facility at Mareesburg in South Africa to ensure zero contamination of ground water. The three-phase approach adopted for construction of this facility will be completed this year.

Fortescue completes autonomous haul truck fleet conversion in Western Australia

Fortescue Metals Group says it has completed its Chichester Hub autonomous haulage project, with 183 trucks now operating in AHS mode across its Solomon and Chichester Hubs, in Western Australia.

The project represents one of the largest fleet conversions to autonomous haulage systems (AHS) in the industry. It was aided by the involvement of Thiess.

The multi-class fleet includes Cat 793F, 789D and Komatsu 930E haul trucks and has safely travelled more than 52 million km and moved 1,500 Mt of material since 2013, according to FMG. An additional 900 assets, such as excavators, wheel loaders and light vehicles, are integrated with the autonomous fleet using Cat MineStar Command for hauling technology, which is operated from the Fortescue Hive, the company’s integrated operations centre in Perth, Western Australia.

Chief Executive Officer, Elizabeth Gaines said, “Mining is one of the most innovative industries in the world, and Fortescue continues to build on our leading autonomy capability to deliver productivity and efficiency benefits.

“Most importantly, the introduction of AHS technology has improved safety outcomes across our operations and we’re very pleased that the team achieved this important milestone in the truck conversion program to the highest safety standards.

“Our approach to autonomy has been to be open and transparent with our plans and to work closely with our team members to offer opportunities for re-training and re-deployment. Around 3,000 Fortescue team members have been trained to work with autonomous haulage, including over 200 people trained as Mine Controllers and AHS system professionals.”

Group President, Resource Industries, Caterpillar Inc, Denise Johnson, said: “Fortescue is a leader in the implementation of autonomous solutions. This important milestone further reinforces the transformation Fortescue has made with autonomy to improve safety, site productivity and machine utilisation. We congratulate Fortescue on this significant achievement.”

Fortescue Chief Operating Officer, Greg Lilleyman, said: “Fortescue’s autonomous haulage fleet has delivered a 30% increase in productivity. Looking ahead, the flexibility of our efficient, multi-class autonomous fleet offers considerable potential for further productivity and efficiency gains.

“Our operations are more connected than ever before and, by using data from our autonomous haulage fleet, we can paint an accurate picture of our operations and focus on the optimal opportunities for improvement, such as haul road design and maintenance scheduling.

“Our autonomous haulage system is a foundational tool which allows us to streamline processes and improve outcomes, ultimately delivering increased value for our shareholders.”

Fortescue’s autonomous haul truck fleet at Christmas Creek still growing

Fortescue Metals Group has now seen 35 manned haul trucks converted to autonomous mode at its Christmas Creek operations in the Pilbara of Western Australia, with Caterpillar recently completing a Command for hauling installation on a Komatsu 930 E, according to the iron ore miner.

The company shared the news ahead of an investor and media tour of the company’s operations this week.

During the tour, attendees will take in details of the company’s new 60.1% Fe product, West Pilbara Fines, in addition to viewing the innovative relocatable conveyor that started operating earlier this year.

Visitors can also expect to see first-hand Fortescue’s roll out of autonomous haulage technology. This includes a global first where Cat Command for hauling, part of Caterpillar’s MineStar technology offering first used on a commercial scale at Fortescue’s Solomon Hub operation, has been retrofitted on a CAT 789D and a Komatsu 930E haul truck.

Chief Executive Officer Elizabeth Gaines said: “Fortescue has led the way globally in embracing automation at our operations. The 789D is the 35th manned truck to be converted to autonomous at Christmas Creek, demonstrating our progress to becoming the only iron ore operation in the world to have a fully autonomous haulage fleet.”

Gaines said the tour will also see the company discuss Fortescue’s new energy agenda, including the integration of renewable energy and its recently announced landmark partnership with CSIRO to commercialise hydrogen technology.
