Rio Tinto Minerals opens new talc beneficiation plant in Australia

Rio Tinto Minerals has inaugurated a new beneficiation plant at its Three Spring Operation, home to the largest talc deposit in Western Australia. It replaces a prior beneficiation plant, which was in poor structural condition. The new facility which cost about AUD 11 million has the capacity to produce up to 150,000 t of ore per year to accurate product specifications and in compliance with best safety standards.

The new facility crushes, screens and washes up to 200 t/h of primary ore, which is then sorted using a more sophisticated representative sampling system. Combined with improved grade control techniques in-pit, the new plant ensures an all-round improvement in product quality, says the company. An integrated flow-sheet reduces double handling, making it more efficient, reducing fine particle generation and enabling a 30 % saving in power consumption.

Three Springs supplies a full range of high brightness, highly pure microcrystalline talc grades to the paint, paper, rubber, and technical ceramics markets.
