Cyanide leaching has been the industry standard for gold processing for more than 100 years. During the cyanide leach process, a cyanide solution, or lixiviant, is percolated through ore contained in vats, columns or heaps. Gold is dissolved by the cyanide and then removed from the heap or columns. It is then extracted from the pregnant leach

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

01.04.1999Gold cyanidation, using hydrogen peroxide, was considered by Knorre et al.

On the other hand, Day [6] found no direct relation between the behavior of the gold dissolution rate and cyanide or peroxide concentrations.
