Sulfide Ore - an overview ScienceDirect Topics

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.

What is Sulfide Mining? Mining Action Group

Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to poison the nearby water ...

Minerals Ores – Blue Sky Metals

Many metallic ores occur as sulfide minerals. Examples of sulfide minerals are galena (lead sulfide, PbS), sphalerite (zinc sulfide, ZnS), covellite (copper sulfide, CuS), or pyrite (iron sufide, FeS2). Galena Sphalerite Covellite Pyrite. These sufide minerals crystallize from the ore-forming fluids at

Characterizing gold in refractory sulfide gold ores and ...

Gold is present in refractory sulfide gold ores mainly in arsenian pyrite and arsenopyrite, where it occurs in both the chemically bonded state and as nano-size grains of metallic gold. During roasting or pressure oxidation, the sulfide matrix is destroyed and essentially all the gold is converted to the metallic form. The liberated gold is readily dissolved in conventional cyanide media ...

2021-8-12  The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
