A "refractory" gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pretreatment in order for cyanidation to be effective in recovery of the gold. A refractory ore generally contains sulfide minerals, organic carbon, or both.

GOLD CONCENTRATOR. During operation, the decreasing height and width of the leads create the classifying effect as the ore passes through the barrel. As the ore is being classified, the gold and heavy concentrate settle into the bottom of the groves made by the leads and is conveyed upwards (in reverse).

Gold ore processing plant: The gravity of gold is rather large, it's more suitable for gravity method (gravity equipment:jigger machine, shaking table,spiral chute, etc.). According to the composition of gold ore,it also can be combined by the methods of amalgam, cyanidation and flotation process to choose the gold.

In the gold ore processing plant, normal gold mining process machines are usually gold ore gravity equipment such as gold ore processing machine of jiggers and concentrating tables. Since gold ore has large density, gold ore processing mainly applying gold gravity separation. Thus gold ore processing equipment of gravity separation machine is very important.

specific gravity than the host rocks that contain the gold [4]. Elemental gold has a specific gravity of, and typical ore has a specific gravity of about All gravity concentration devices create movement between the gold and host rock particles in a manner to separate the heavy pieces from the lighter pieces of material. Panning is probably the oldest technique used for the recovery of gold. Panning is a type .
