The Grasberg Mine, owned by Freeport-McMoRan, has long been the source of some controversy, with contractual disputes halting operations at the world’s second largest copper mine.

The mine has been a source of controversy due to the revenue share that both Indonesia and Papua get, as well as a lack of clarity over the impact of its tailings and water systems.

The Grasberg Mine

The Grasberg Mine is part of the Grasberg minerals district, which is home to a number of open-pit and underground mines.

Located in the remote highlands of the Sudirman Mountain Range in the province of Papua, Indonesia, the Grasberg mine was discovered back in 1988. After years of production, the mine stands as one of the world’s largest recoverable copper reserve and the largest gold reserve.

Freeport owns 90.64 percent, which is also made up of 9.36 percent owned through the subsidiary, PT Indocopper Investma) and 9.36 percent of the Government of Indonesia.

Production began at the Grasberg open-pit back in 1990. Crushing and conveying systems are integral to the mine and provide the capacity to transport up to 150,000 mtd of ore to the mill and 75,000 mtd of overburden to the overburden stockpiles. The remaining overburden is moved by haul trucks

Freeport has several projects in progress at the Grasberg district, which over the next few years are expected to process an aggregated amount of 240,000 metric tons of ore per day.

BHP, Rio Tinto & Vale launch 'Charge On' Innovation Challenge - a competition for tech innovators to reduce truck emissions via electrification

Mining giants BHP, Vale and Rio Tinto have launched the 'Charge On' Innovation Challenge to solve one of the biggest challenges the industry faces today - decarbonising mining operations.

'Charge On' Innovation Challenge

In partnership with Austmine, Australia's leading mining equipment, technology and services industry association, founding patrons BHP, Vale and Rio Tinto have launched the competition to encourage technology innovators to develop new concepts for large-scale haul truck electrification systems. The main goal is cutting emissions from surface mining operations.

“The mining industry needs to be at the forefront of tackling the climate challenge. The Charge On Innovation Challenge is a great example of the current collaborative work being done by the mining industry and mobile equipment manufacturers to decarbonise mining fleets,” the trio said in a media statement.

“In addition to providing a zero-carbon energy source, the conversion of mobile mining equipment to battery-electric can potentially unlock value, as electric motors have fewer moving parts when compared to standard equipment.”

A number of non-traditional mining sector vendors are actively developing technologies that can assist in mine electrification. By submitting a Challenge to the market, the Patrons of Charge On expect to:

  • Demonstrate there is an emerging market for charging solutions in mining
  • Accelerate commercialization of solutions
  • Indicate to suppliers, the mining industry seeks interoperable solutions
  • Maintain multiple actors and competition in the supply chain
  • Integrate innovations from other sectors into the mining sector

"We expect some solutions identified in the Challenge could provide propulsion to existing diesel-electric trucks. This may present a pathway to early implementation for dynamic charging solutions," the trio said.

Paris Agreement

Found patrons BHP, Vale and Rio Tinto are pledging their commitment to fighting climate change:

"The mining industry has an important role to reduce emissions and do our part to achieve the Paris Agreement goals to limit the impacts of climate change."

The Charge On Innovation Challenge asks vendors to present interoperable solutions that can safely deliver electricity to large battery-electric off-road haul trucks in a way that maintains or improves current productivity levels. Specifically, mechanisms capable of delivering in the order of 400kWh of electricity to each truck within a haul cycle (ie load, travel, dump, return, queue). The delivered electricity is to charge a battery, and if applicable directly propel the truck.

Austmine CEO Christine Gibbs Stewart commented: “We expect the Challenge will attract companies from a broad range of sectors including mining, automotive, aerospace, agriculture, and defence to deliver selected charging concepts to create a standard product that can interface with all trucks."

More information about the challenge will be released on May 18.

Electrification

The competition echoes growing efforts being made across the industry to tackle emmissions and promote electrification. In march this year, the Electric Mine Consortium was launched. It's founding members include Gold Fields, Dassualt Systemes and Sandvik who pledged their commitment to decarbonising mining operations.
