Sulfide Ore - an overview | ScienceDirect Topics
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 ...

Copper extraction - Wikipedia
All primary sulfide ores of copper sulfides, and most concentrates of secondary copper sulfides (being chalcocite), are subjected to smelting.Some vat leach or pressure leach processes exist to solubilise chalcocite concentrates and produce copper cathode from the resulting leachate solution, but this is a minor part of the market.. Carbonate concentrates are a relatively minor …

Smelting - Wikipedia
Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.
