Orica to deliver tech and blasting services to Glencore’s Australia copper, zinc ops

Orica says it has been awarded a five-year explosives technology and services contract for Glencore’s Australia copper and zinc operations, effective January 2021.

Glencore, one of the world’s largest globally diversified natural resource companies, produces and markets a diverse range of metals and minerals, with its Australia copper and zinc operations including McArthur River Mine (Northern Territory), Lady Loretta Mine (Queensland), Mount Isa Mines (Queensland), Ernest Henry Mine (Queensland) and CSA Mine (New South Wales). Orica has an existing supply agreement with Glencore’s nickel and cobalt operations at Murrin Murrin, in Western Australia.

As part of the contract, Orica will deliver the full suite of explosives technology and blasting services across the Glencore copper and zinc operations in Australia, including supply of the fully wireless initiating system, WebGen™, BlastIQ™ digital blast optimisation suite of products and smart explosives delivery system, Bulkmaster™ 7.

This partnership further strengthens and expands Orica’s longstanding relationship with Glencore, the manufacturer of commercial explosives and innovative blasting systems said.

Orica Chief Executive, Alberto Calderon, said: “Glencore is a key global diversified customer, and we are delighted to be partnering with them across their Australian copper and zinc operations, integrating our most advanced technologies and solutions to solve their more complex operational needs.

“Glencore’s Ernest Henry mine in northwest Queensland was the first site in the world to trial and adopt our wireless explosives technology, WebGen. This deal shows Glencore’s confidence in our technology roadmap as well as aligning with their strategic vision for technology to deliver added value to their operations.”

Orica will work closely with Glencore to ensure uninterrupted supply to each operation, during the rapid mobilisation and transition period, it said.

Murrin Murrin nickel mine to benefit from new Bis road trains

As part of a major upgrade to its off-road haulage fleet at Minara Resources’ Murrin Murrin nickel mine in Western Australia’s north-eastern Goldfields, Bis’ operational teams have welcomed new 350 t Dual Powered Road Trains (DPRTs) to site.

Bis’ high-payload proprietary road trains deliver customers reduced haul cycles and vehicle movements – leading to higher productivity at reduced costs, the company says.

Bis has been providing a range of services at Murrin Murrin (wholly owned by Glencore), including haulage and haul and road maintenance services, calcrete services, and bulk logistics services, since the operation began in 1998. Last year, it extended its haulage and site services contract for a further four years.

Bis’ Rexx 20-wheel dump truck impresses at Glencore’s Murrin Murrin mine

Bis Industries says its “revolutionary” new mining haul truck has delivered outstanding results in trials at Glencore’s Murrin Murrin nickel mine in the north-eastern Goldfields of Western Australia.

Known as Rexx, the dual powered 20-wheel dump truck has been designed with a range of features specifically incorporated to deliver savings to Bis customers, the company said. Rexx has more than four times the range of conventional dump trucks, outstanding manoeuvrability, operator comfort and maintainability plus on demand power that lowers fuel consumption, according to Bis.

Bis CEO Brad Rogers said the testing at Murrin Murrin mine has been carried out in `real-life’ operating conditions and the results to date indicated Rexx had the capacity to deliver up to a 30% reduction in operating costs compared with conventional dump trucks. These savings will be delivered to miners as part of Bis’ integrated haulage solution, it added.

Rogers said one area of the savings that could be passed on to Bis customers in haulage costs was average fuel use by Rexx, which was around half the fuel consumed by equivalent competing dump trucks.

“The fuel savings are a direct consequence of Rexx being designed with patented on-demand power that lowers fuel consumption,” the company said. “The vehicle has the capacity to carry enough fuel for at least two 12-h shifts, eliminating downtime needed for refuelling.”

Rogers said Rexx had been designed in-house by the Bis engineering team while the construction had used the talent of Western Australian tradespeople.“In Rexx we have a game changing work horse that showcases Australian innovation,” he said.

For example, the steering system enables an industry leading turning circle of just 13.5 m, allowing Rexx to manoeuvre easily in smaller spaces, the company said.

With an eye to industry trends, Rexx had also been designed and built to be easily retrofitted for autonomous operations with features including steering sensors, stability control sensors and a futuristic in-cab console, Rogers said. The console provides the operator with real-time data including pressure monitoring on all tyres and sensors for detecting bin tipping, engineering operation and payload.

Mining Manager at Murrin Murrin, David Ayres, said: “We were thrilled to be involved with Bis on this exciting project. Outside of autonomous systems, there haven’t been many major fundamental design changes in the rigid-frame off-highway game in a long time.

“The Bis design offers the ability to haul directly from pit-to-plant from a much longer distance, without the need for the re-handle step, which should save costs and reduce ore loss/dilution. Rexx solves a niche haul-distance equation,” he said.

Rexx has sparked significant interest from major miners both internationally and within Australia and a series of demonstrations are now being staged with interested customers, Bis said.
