agitation leach gold

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

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

How to Fix Agitator Mixer Problems in a Gold Leach Circuit

This design problem caused solids to build up around the walls and bottom of the leach tank reducing the effective size of the tank and lowering the actual leaching time for the active slurry. This reduction in leach time ultimately resulted in lower gold recovery. To get more agitation the agitator impellers were sped up.

The development of fundamental laws governing the operation is compli ed by the large number of variables involved some of which can hardly be evaluated in mathematical terms

Gold Agitation Cyanidation Leaching - cnlitereagent.com

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.

Agitation Leaching Theory And Practice Biology Essay

Increasingly agitation leaching is being considered to treat very finely ground materials and with the advances in ultrafine milling equipment have been ground to lesser particle sizes to liberate gold contained in refractory along with the sulphide mineral matrices prior to processing by agitation leaching and/or oxidative pre-treatment.

Leaching Agitation Tank - prmepc.com

A gold processing plant in Shanxi was built in 2010 the capacity is 200 t/d and adopted direct cyanide——zinc dust precipitation process. Due to the stirrer paddle of previously installed double impeller agitation tank is a bit small the speed is low and pulp agitator is uneven which are against gold leaching.

settling out bogging the tanks. Agitation also ensures that the gold cyanide complex ions forming on the surface of a gold particle are removed into the wider solution to allow ‘access’ on the gold particles’ surface for more unreacted cyanide ions to leach more gold from the particle. Temperature Higher temperatures will increase the
