Base Metal Ores - an overview | ScienceDirect Topics

Compared to base metal ores, iron ores are low-value products, and therefore, large tonnages have to be treated to make the upgrading process economically viable. This makes the flotation process, which is ideally suited for treating large tonnages of low-grade material, by far the best option for most of the ores currently being mined.

In Pergamon Materials Series, 1998. 10.6.6.1 Matte-slag-gas reactions in Cu-Fe-Ni sulphide ores. Sulphide ores are a major source of Cu, Ni and precious metals. A basic principle of the extraction processes is to blow air into the molten sulphide in order to oxidise (1) S, which forms a gas and (2) Fe, which forms predominantly FeO and then partitions to a slag phase which covers the matte.
