Chat OnlineGold has varying modes of occurrence in sulphide ores ranging from being disseminated and interstitial in minerals such as lead and copper in oxide ores particularly as disseminated particles and as free milling gold or association with tellurides.
Chat OnlineThe sulfide minerals are a class of minerals containing sulfide (S 2−) or persulfide (S 2 2−) as the major anion. Some sulfide minerals are economically important as metal ores. The sulfide class also includes the selenides the tellurides the arsenides the antimonides the bismuthinides the sulfarsenides and the sulfosalts.
Chat OnlineA volcanogenic massive sulfide deposit forms by deposition of sulfide minerals on the seafloor associated with seafloor magmatism. Convection drives cold seawater downward where it heats and dissolves metallic elements to return to the surface at hydrothermal vents. Cooling of the hydrothermal fluids causes precipitation of metal sulfide minerals.
Chat OnlineGold 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.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing resulting in direct recovery of
