The Queensland goverment will ensure the viability of Australia’s second-largest aluminium smelter near Gladstone as it transitions to renewable energy.

The new facility in Western Australia is expected to use raw biomass and microwave energy to convert iron ore to metallic iron in the steelmaking process.

The mining giants will work with Caterpillar and Komatsu to conduct independent trials of the battery-electric haul trucks.

Their first focus will be on the potential development of a solar power generation facility.
