Supergene (geology) - Wikipedia

2019-10-14  In ore deposit geology, supergene processes or enrichment are those that occur relatively near the surface as opposed to deep hypogene processes. Supergene processes include the predominance of meteoric water circulation with concomitant oxidation and chemical weathering.The descending meteoric waters oxidize the primary sulfide ore minerals and redistribute the metallic ore

Gold extraction - Wikipedia

2019-10-27  Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.[1] Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold

Oxidation Reduction Effects in Depression of Sulfide

Oxidation of Sulfide in The Absence of Collectors Or DepressantsDepression of Sulfide MineralsSummary DiscussionPourbaix diagrams, also known as the Eh-pH diagrams, provide a comprehensive and concise representation of oxidation-reduction reactions based on thermodynamic data. Calculation of such diagrams requires a priori knowledge of the reaction products and the assumption that thermodynamic equilibrium prevails. Non-equilibrium conditions are not too uncommon for the reaction of sulfide minerals in aqueous solutions. The non-equilibrium conditions may arise because of several reasons: formation

Sulfide Mineral Oxidation SpringerLink

Sulfide mineral. A metal-sulfide compound, such as pyrite (FeS 2), which forms at high temperature (>50°C) in well-crystallized veins or masses and at low temperatures (<50°C) in poorly crystalline and fine-grained particles.. Oxidation. The chemical process of reacting with oxygen. More generally, the chemical process of removing electrons from an atom or group of atoms.
