gold cil leaching tank

Due to the inherently low concentration of gold in ore and the relatively long retention time required for gold to dissolve, gold cyanide leaching reactors are usually very large, with a size of up to 5000 m3 For the same reasons, the solids content in tank leaching is kept at a high level, around 40 wt

Approximately 85 of the gold is recovered in the plant From the ball and/or autogenous mill, slurry is pumped to the CIL leach tanks where lime adjusts the pH, if necessary, and it is agitated for the desired period of time Air is added to increase the reaction rate and shorten the leach time Cyanide is added, typically in the first tank

CIL gold processing plant mainly consists of following steps: 1 The ore is first reduced in size typically 90 passing 200mesh to ensure that all non refractory gold is readily accessible for cyanide leaching, There are several variations of comminution circuits used in the gold leaching industry, such as: Multi stage crushing, then ball milling circuits, typical of ball mill and hyrocyclones

Spent Ore from Tank Leaching Tailings:Tank leaching, both CIP and CIL circuits, generate spent ore by leaching the gold values from finely ground ore The spent ore exits the leach circuit as a slurry composed of gangue and process water bearing cyanide and cyanide metal complexes The tailings
