cyanide heap leach process

An Overview of the EnviroLeach Gold Recovery Process

The standard leach protocol using 1 g/t cyanide resulted in 90.6% gold recovery into solution. Raising the cyanide concentration to 20 g/l increased gold recovery to 97.9%, reflecting the need for a more aggressive or intensive leach environment for this type of high grade, coarse, gravity concentrate.
