Metal Sulfides - an overview | ScienceDirect Topics

Structure is related to the ability to lubricate and the oxide formation is related to the change from a soft material to a harder one. The true sulfide lubricant is the famous MoS 2, which forms layers with an interplanar distance of 3.49 Å and can lubricate until is transformed to MoO 3 in air above 500 °C. The sliding properties of MoS 2 are due to the weak interactions between the sulfur ...

Sulfide Minerals - an overview | ScienceDirect Topics

Mining of metallic ores has, in the past, involved smelting whole rocks, though the advent of concentration techniques (mostly involving froth flotation and separation of target minerals) and nonpyrometallurgical techniques (such as pressure oxidation and biological processing) have had, and continue to have, a major impact on the mining industry.

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 ...

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 ...
