  • What is Gold Cyanidation? (with picture) wiseGEEK

    23.09.2020· Gold cyanidation, also called cyanide leaching, is a process used to extract gold from raw ore taken from the ground. It uses cyanide to dissolve the gold within the rock, which, itself, is not soluble in cyanide. The gold is then drawn out in a liquid form that can be treated to remove the cyanide. Almost 90% of all gold extracted commercially is done so by cyanidation. The process has been

  • Cyanidation of a copper-gold ore ScienceDirect

    Without lead nitrate, the gold recovery is lower than 90% but with lead nitrate, it reaches 98%. The addition of oxygen increases the gold recovery by 1.5%. The extraction of gold is not sensitive to lead nitrate additions when higher than 300 g/t. The redox potential values could thus be used as control parameters for lead nitrate addition, at the different stages of cyanidation, to indicate
