Historically Carlin Type Gold Deposit are big elephants but until recently they were largely known to occur only in the limited hunting ground of Northern Nevada that limitation is now beginning to change.. How Carlin gold deposits fit into the overall scheme of things.
Read MoreOre processing technologies extract economically valuable minerals and metals. They include the collection of naturally occurring metals and minerals (e.g., placer gold or lode silver), crushing and grinding ores, mechanical concentration of ores containing metals and minerals, and breaking down the ores with chemical, heat, and electrical ...
Read MoreThe principal gold minerals that affect the processing of gold ores are native gold, electrum, Au-Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the Au-Ag tellurides, and very fine-grained gold ( 10 m) locked ...

Read MoreWhen gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators.
Read MoreDor bars are unrefined gold bullion bars containing anywhere from 60 to 95 percent gold. We finally send the bars to a refinery for further processing into pure gold. Alternative Ore Processing. We use alternative gold recovery methods in some processing plants to accommodate different ore characteristics or other requirements.
Read MoreSep 07, 2017 At current gold prices this is worth about US$600. Both smelter treatment charges and oxidation or bio-leach costs are at least $200/t of concentrate and payables/recovery in the 90% range, so a minimum GSR for effective downstream processing is around 0.5. Clearly this is a function of gold price, but in the current gold price and cost ...
