Refining ore Rio Tinto

The new plant crushed the ore into smaller pieces to remove more gangue, and then roasted it in rotary furnaces to reduce the sulphur content. In 1982, we added a magnetic separation process to improve the refining process further. The result was a richer titanium slag, with nearly ten per cent higher levels of iron and titanium oxides.
