First Quantum to operate world’s largest ultra-class truck trolley fleet with Liebherr T 284

The day after announcing it will accelerate the implementation of its existing low carbon solutions and trigger future projects at MINExpo 2021, Liebherr has confirmed that it will supply a further 11 T 284 trucks to operate on trolley lines at First Quantum Minerals Limited (FQML)’s Sentinel and Cobre Panama mines with the miner claiming, in the process, the title of the world’s largest ultra-class truck fleet on trolley.

In 2013, Liebherr received an initial request from FQML to develop a 360 t trolley-capable haul truck for mine sites in Panama and Zambia. The trucks were required to integrate with the trolley power line that FQML had designed and developed for the sites.

Agreeing to this partnership, Liebherr engineers began developing, testing and verifying the trolley solution. Two Liebherr T 284 trucks with the Trolley Assist System were commissioned at Sentinel copper mine in Zambia in 2016 and testing of the trolley solution began in February of 2017, with 12 months allotted for the customer to evaluate the trucks, the trolley and the customer service.

At the end of the trial period, FQML expressed it was pleased with the results of the Trolley Assist System and the performance of the T 284, leading to an order for six more trolley-capable T 284 trucks at Sentinel mine, along with 30-trolley-capable T 284 trucks for Cobre Panama copper mine in Panama, Liebherr says.

As a mark of success of the partnership between FQML and Liebherr, along with the performance of the T 284 with trolley solution, FQML recently confirmed an order for a further 11 T 284 trucks. These three trucks for Sentinel mine and eight trucks for Cobre Panama mine will join the existing fleets operating with the Trolley Assist System. This soon-to-be fleet of 38 T 284s in Panama will claim the title of the world’s largest ultra-class truck fleet on trolley, according to Liebherr.

“Trolley Assist truck systems have become integral to the development of First Quantum’s large scale open-pit truck haulage operations,” an FQML representative says. “Over the last decade, First Quantum has emerged as one of the industry leaders in implementation of Trolley Assist systems across mine planning and design, installation, operations, and maintenance. We consider our purpose designed Trolley Assist systems deliver a step change in measurable haulage performance through increased truck productivity, improved maintenance cost, and reduced carbon emissions.

“During the past five years, Liebherr has proven itself as a proactive partner in the development of Trolley Assist capable truck fleet systems. First Quantum has selected the Liebherr T 284 ultra-class truck for some of our Trolley Assist deployments at our large-scale mining operations in Zambia and, more recently, as the sole deployed truck at our Panama mining operations. With a high degree of co-operation between our organisations, we see this partnership continuing to grow in years to come.”

Oliver Hoelzer, Director of Mining Liebherr-Panamá, says: “Even before the arrival of the very first truck, Liebherr Panama’s relationship with FQML Panama has been more of a mutual partnership than a pure business relationship. Our highly committed team recognises that Liebherr’s own success is intrinsically linked to the success of FQML.”

Liebherr has also delivered six trolley-capable 100 t T 236 haul trucks to the Erzberg iron ore mine in Austria, bringing the total number of Liebherr trucks with the Trolley Assist System to 56 once FQML’s newest fleet has been commissioned.

Liebherr aims to offer fossil fuel free solutions for its entire digging, dozing, and hauling product range by 2030.

GIW MDX-750 keeps slurry moving at Panama copper mine

GIW Industries says its recent success with a customer at a Panama copper mine bodes well for the future of copper mining in Central America and the pump manufacturer’s potential for business in this area and beyond.

The Panama copper mine customer needed to ensure continuous and efficient operation of its mine and, according to GIW, was looking for a dependable partner with experience in the market, a good track record in similar applications and excellent technical support.

Reliable parts supply was at the top of the priority list, GIW said, while it also needed a company that could help solve their system challenges and offer continuous improvements.

GIW said: “The customer was familiar with GIW’s success in Chile with the MDX-750 slurry pump and wanted to achieve the same performance.”

GIW supplied a customised MDX-750 pump – one of the world’s the largest mill pumps – featuring all the latest slurry handling technology, it said. In addition to GIW’s long-lasting wear materials, the company included technology to allow the company to monitor vibrations and check the temperature of the bearings.

The company added: “GIW design engineers converted our traditional imperial threads to metric, and all seal configurations have been customised to the customer’s specifications. In the future, the customer will have the capability to test the oil quality and assess parts’ wear life. They also have the ability to optimise their pump by adding GIW’s remotely adjusted mechanical suction liner (RAMSL) feature.”

The RAMSL function allows for efficient pump operation in aggressive wear applications, according to GIW.

Benefits of the MDX pump include increased output, reduced downtime and easier maintenance, the company says. This increased efficiency and a longer wear life results in a lower total cost of ownership.

This success is an example of GIW’s ability to provide reliable service around the world, it said, with GIW collaborating with its parent company’s (KSB) teams in Australia and Central America to coordinate the engineering and delivery of the pumps to site.

First ore for FQM’s Cobre Panama copper mine

First Quantum Minerals has introduced first ore to the processing plant at its 74 Mt/y Cobre Panama open-pit copper mine in Panama.

On February 7, ore was introduced through primary crushing and onto the stockpile with initial feed rates between 4,000-5,000 t/h. Then, on February 11, ore was introduced through to the first milling circuit.

Operation on ore continues and will move into all other sections of the processing plant including producing copper concentrate, according to First Quantum. The company is now focused on an efficient phased ramp-up for Cobre Panama continuing through 2019.

At full tilt, Cobre Panama is expected to produce 350,000 t of copper from an in-pit crushing and conveying set up that includes four box cuts with semi-mobile primary crushers – two per conveyor line – feeding two in-pit conveyor lines that feed two overland conveyors after a transfer station to the secondary crushing and the main process plant. The company uses a fleet of Komatsu Mining P&H 4100XPC electric shovels; 363 t Liebherr T 284C trucks, Komatsu Mining Le Tourneau L2350 large wheel loaders (with SR drive), Liebherr R 9350 hydraulic excavators and Cat 777G 100 t trucks at the operation.
