Gold Agitation Cyanidation Leaching - cnlitereagent

18-10-2019  Definition of Agitation Cyanidation Leaching. The agitation leaching method is to concentrate the slurry, obtained after grinding and classifying of the gold-containing ore, to a suitable concentration, place it in a leaching tank, add a cyanide solution, and aerate to carry out leaching. The main equipment used in the agitation leaching process is a cyanide leaching tank.

The process design of gold leaching and carbon-in-pulp ...

Leaching takes place in a series of agitated leach reactors or pachucas. Before leaching the pH of the pulp is normally adjusted to a value of around 9.5–11 to ensure minimum loss of cyanide as hydrogen cyanide. The leaching of gold can be conveniently represented by the Elsener equation: [1] Although air agitated leach tanks were commonly used in

oxygen are required in an aqueous solution in order to leach gold. For the leaching of pure gold, the stoichiometry of Elsner’s reaction gives the required molar ratio of free cyanide to oxygen as 8:1 (or 61/ 2:1 when expressed as a mass ratio). Since cyanide is the more expensive reagent, it is desirable from a financial point of view to ensure that

Tank leaching - BioMineWiki - Skelleftea.se

Stirred tank bioleaching is mainly applied on refractory gold concentrates with gold concentrations in the range 10-150 g/tonne. In a refractory gold concentrate very fine gold particles are locked into the sulfide matrix and to liberate the gold for subsequent recovery by cyanide leaching the sulfides have to be leached.
