Leaching Agitation Tank xinhaiepc

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

Metallurgical ContentLearn CyanidationDevelopments in the Carbon-In-Pulp ProcessDesign Criteria Commercial Operations Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a

Leaching Low-Grade Gold Ores SpringerLink

Multistage agitation leaching followed by elaborate solids-liquid separation is required to recover most of the gold (up to approximately 95%) in solution, in a reasonably short time (see Chapter 4). Large tonnage of a relatively high-gold-content ore is a prerequisite for the substantial capital and operating costs required for milling.

US5336474A Process for leaching of precious metals

A process is disclosed for the leaching of gold and silver from ores and ore concentrates through intimate contact of the ore or ore concentrate with an aqueous leach solution containing cyanide. The leach solution has a pH of 8 to 13. The leaching process takes place in the presence of an oxygen-releasing peroxo compound. The separation of the formed cyano complexes of gold and silver takes

Alkaline cyanide leaching of refractory gold flotation

Specifically, the influence of ore mineralogy, pH modifier (caustic soda and quicklime), agitation rate (600–1000 rpm) and time on the leaching behaviour has been studied at 30 °C and pH 10.5 ± 0.2 over 8 h period. The results showed that cyanide leaching of the refractory flotation concentrates did not significantly alter the ore
