About this site

Platinum-group element concentrates are made into a matte that is relatively low in iron and sulfur, and enriched in platinum-group elements by smelting and converting. Smelting removes most gangue minerals as molten slag. Converting removes most iron and sulfur by oxidation with air and oxygen. In combination, these two steps upgrade the feed ...
