Gold Cyanidationfor Mining

Size of gold grains. The size of gold grains dissolution mainly affects the cyanide time. If the gold grains is larger than 74 micron, the dissolution rate of gold will be slowed down. Therefore, it is reasonable to recover the coarse gold by amalgamation, gravity separation or flotation before cyanidation process.
