  • Sulfide Ores an overview | ScienceDirect Topics

    VMS ore-forming fluids are acidic, reduced, 1–3 M chloride solutions in which metals were transported mainly as chloride complexes (Table 3).Before the discovery of black smokers, temperatures of the ore fluids were estimated from rare fluid inclusion data and sulfur isotope fractionation between sulfide mineral pairs. pH values about 1 unit less than neutral (~5 at 250 °C) were determined

  • sulfide mineral | Definition, Examples, Identification

    The composition of the sulfide minerals can be expressed with the general chemical formula A m S n, in which A is a metal, S is sulfur, and m and n are integers, giving A 2 S, AS, A 3 S 4 and AS 2 stoichiometries. The metals that occur most commonly in sulfides are iron, copper, nickel, lead, cobalt, silver, and zinc, though about fifteen others enter sulfide structures.

  • Mineral Processing & Metallurgy

    Ferric sulfate and chloride have been frequently employed as oxidants. Other oxidants that appear compatible with acidic thiourea systems include Na2O2, O3, KBrO3, and K2Cr2O7. Like the metallic form, certain silver minerals require oxidizing conditions for dissolution in acidic solutions. Argentite (Ag2S) in the presence of thiourea is leached by ferric ions according to the following overall

    Gossans form by the oxidation of the sulfide minerals in an ore deposit and they thus may be used as clues to the existence of subsurface ore deposits, especially if distinctive boxworks are present. In addition to hydrous oxides of iron and manganese, gold and silver in the native (natural, nearly pure) state and various sulfate, carbonate, and silicate minerals can occur in gossans.
