The Grinding Fineness

Cyanide leaching process is one of the common gold ore beneficiation processes. The process index depends on factors such as gold particle size, sulfide content, ore block size, leaching speed, leaching time, cyanide concentration and leaching slag washing degree. The factors that affect gold leaching include grinding fineness, pH, temperature, cyanide dosage, pulp-solid-liquid ratio, leaching time, impurities in ore and amount of leaching …

The Effect Of Grinding Chemistry On Cyanide Leaching Of ...

Pyrrhotite commonly occurs in many gold ores together with pyrite and/or arsenopyrite. A synthetic ore was prepared by mixing pyrrhotite with gravity gold concentrate and quartz. Pyrrhotite is of interest to grinding and leaching chemistry because this sulfide mineral is the highest cyanide- and oxygen-consuming iron sulfide and, contrary to pyrite, tends to behave as a reactive anode.
