Intrusive related gold usually also contains copper, and is often associated with tin and tungsten, and rarely molybdenum, antimony and uranium. Intrusiverelated gold deposits rely on gold existing in the fluids associated with the magma (White, 2001), and the inevitable discharge of thesehydrothermal fluids into the wallrocks (Lowenstern, 2001)....

Mar 26, 2011· Abstract. Leaching from silver sulfide using a copperthiosulfate solution in the absence of ammonia was investigated. It is found that silver sulfide could be effectively dissolved in the copperthiosulfate system without ammonia. The effects of thiosulfate concentration, copper tothiosulfate ratio, agitation vigorousness, pH values,......

Geology of Gold Mineralization How Gold Deposits are Formed
The Geology Of Gold Gold is relatively scarce in the earth, but it occurs in many different kinds of rocks and in many different geological environments. Though scarce, gold is concentrated by geologic processes to form commercial deposits of two principal types: lode (primary) deposits and placer (secondary) deposits....
Catalytic Oxidation Pretreatment of SulfideRich Arsenic ...
This paper summarizes the result of experiment that was fourced on investigation of oxidation pretreatment on sulfide mineral for leaching of refractory gold concentrate by hydrogen peroxide in sulfuric acid. For a viable option, extraction rate of Fe, Cu was low, but extraction rate of arsenic reached nearly . As the result of oxidation, elemental sulfur was not produced....

Sulphide Gold | Gekko
Preconcentration of coarse 350 – 500 micron sulphideassociated gold ore, using the InLine Pressure Jig, is required to reject gangue from the high value material. The IPJ, a classic preconcentration device, is effective in gangue rejection prior to further processing of valuable goldbearing material....

USA Process for removing and recovering copper ...
Ores containing copper, zinc, silver in the form of sulfides are treated by a solution of sulfurated sulfite ions and ammonium ions in order to remove most of the metals from the sulfide ores. This treatment renders the resulting gold bearing ores much more amenable to cyanide extraction. Dissolved metals are reclaimed by appropriate techniques, such as electrowinning or liquidliquid ......
