The standard cyanide leach process consists of grinding the ore to about. 80% – 200 mesh, mixing the ore/water grinding slurry with about 2 pounds. per ton of sodium cyanide and enough quick lime to keep the pH of the solution. at about 11.0. At a slurry concentration of 50% solids, the slurry passes.
Autoclave pressure oxidation (POX) is an effective pre-treatment option when extracting gold from refractory ore bodies, such as pyrite and arsenopyrite. While gold processing plants are the most common utilizers of POX technology, the process can also be applied to other metals, like copper, zinc and uranium. Valmet has a wide range of valves ...

Autoclaves - Cromtek. La esterilización es el proceso mediante el cual se alcanza la destrucción o eliminación de todas las formas de vida microbianas incluyendo las bacterias y sus estructuras. El autoclave de laboratorio está formado por un recipiente en el que el vapor circula a alta presión y que tiene la finalidad de la esterilización.
the extraction of the refractory gold [9]. In the Kittilä case, the gold loss associated to carbon prefloat before the autoclave treatment is low because of the lack of the preg-robbing. Consequently, any gold losses during flotation would be the result of gold association in the original ore with the prefloat tails.
