Sulfide ore: refers to any type of ore in which the ore minerals are in the form of metallic sulfides. Commonly used for a subgroup of refractory gold ore mineralized rock in which much of the gold is encapsulated in sulfides and is not readily amenable to dissolution by cyanide solutions associated with sulfide minerals (primarily pyrite) that have not been oxidized.

Gossan, rustcoloured oxide and hydroxide minerals of iron and manganese that cap an ore deposit. 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.

Crushed ore or concentrates was fed slowly over the plate, and gold adhered to the mercury. Using "open system" methods like these where any mercury lost through the system went out with the tailings into the environment would be crazy today, and simply an invitation for a big dollar citation from every environmental agency that has jurisdiction over you.

Shortly after arriving in the New World, Nephi reports making "plates of ore" to engrave his account on (see 1 Nephi 19:1).Although he does not tell us specifically which kind of ore he used, just before making the plates he mentions finding "all manner of ore, both of gold, and of silver, and of copper" (1 Nephi 18:25).1Today, readers typically read these statements separately, due to

· An oxide gold ore was subjected to chloride/hypochlorite leaching at room temperature. The effects of three factors, including Ca(OCl) 2 vs. NaOCl, OCl − concentration, and HCl concentration on gold leaching performance were investigated. Due to formation of CaOCl + complex in solution and hence less reactivity, calcium hypochlorite produces a sluggish gold leaching kinetics, taking twice

Copper Ores natural mineral formations containing sufficient copper to make economically feasible the extraction of the metal from these ores. Of the 170 known copperbearing minerals, 17 are currently used on an industrial scale: native copper, Cu; bornite (peacock ore), Cu5FeS4 chalcopyrite (copper pyrite), CuFeS2; chalcocite (copper glance), Cu2S

Gold, recognizable by its yellowish cast, is one of the oldest metals used by humans. As far back as the Neolithic period, humans have collected gold from stream beds, and the actual mining of gold can be traced as far back as 3500 , when early Egyptians (the Sumerian culture of Mesopotamia) used mined gold to craft elaborate jewelry, religious artifacts, and utensils such as goblets.

Biomining, the biotechnology that uses microorganisms to extract metals from ores and concentrates, is currently used exclusively for processing reduced ores and mine wastes. Metals of economic value also occur extensively in oxidized ores, such as nickel laterites. While these are not amenable to oxidative dissolution, the ferric iron minerals they contain can, in theory, be disrupted by iron

When gold dissolution is complete, the goldbearing 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.
