Simulation of leaching process of gold by cyanidation

This paper presents a simulation study of leaching process of gold by using HSC Chemistry software (HSC). Cynide (NaCN) has been used to recover gold from gold bearing ores since 1890’s and until today it still playing an important role in the beneficiation process of the gold. This work aims to dev...
