If the gold can not be concentrated for smelting, then it is leached by an aqueous solution: . The cyanide process is the industry standard.; Thiosulfate leaching has been proven to be effective on ores with high soluble copper values or ores which experience preg-robbing: the absorption by carbonaceous components which preferentially absorbs gold and gold-cyanide complexes.

20 µm. Therefore with decreasing grain size, higher leaching efficiencies are expected. The main fraction of the feed material is below 63 µm, which represents a satisfactory value compared to the grinding effort. Apart from improved the leaching rate, grinding is necessary to allow uniform sampling of the monolith.

Gold Cyanide Solution, Laboratory Bottle Test Method This is one method for doing cyanide bottle leaching tests for determining the 'leachability' of gold and silver by leaching with cyanide. Take the ore to be leached and crush it to a size that will fit into a pulverizer (usually -1/4"). Then feed the ore to a pulverizer and grind to -100 mesh.

Gold processing - Gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for ...
