Australia's Rio Tinto to invest $1.9 billion in Queensland bauxite project
Rio Tinto plans a $1.9 billion investment in the Kangwinan bauxite project in Queensland, Australia, to replace output from its ageing Andoom mine and increase annual production capacity to 44 million tonnes by 2032. The project, targeting first output in 2029, will support the company's Weipa operations and offset the 2029 closure of the Gove mine. This follows Rio's agreement to acquire the adjacent Aurukun Bauxite Project.
