Rio Tinto will reduce Yarwun's alumina production by 40% starting in October 2026, to prolong the plant's life.

Rio Tinto, Australia's largest alumina refinery company, announced on Tuesday that it would cut production at its Yarwun plant in Queensland by 40 percent starting October of next year. This will extend the life of the plant to 2035 while allowing time for modernization.

Under current production rates, Yarwun’s tailings storage facility, which is used to store mining waste, will reach full capacity in 2031.

The company said it had looked into options for a new tailings facility but that the required investment was "substantial" and "not currently economically viable."

Rio Tinto stated that the reduction will affect around 180 positions. It added that it was actively working to relocate and reassign employees who are affected. According to the company, about 725 employees work at the refinery.

The company stated that the production cut would reduce annual alumina production by approximately 1.2 million metric tons, but assured customers that their needs will not be affected. In 2024, the company expects to produce 7.3 million tonnes.

Rio Tinto said that its bauxite mining operations and aluminium smelters would continue to run at full capacity.
