process at the Homestake Mine in Lead South Dakota in 1897 [6]. In 1918, the vacuum de-aeration tank was in-troduced by T.B. Crowe and was incorporatedinto the Merrill process to make the Merrill -Crowe process. This was the removal of dissolved oxygen, which caused zinc passivation making it almost impossible to filter [8].
Once the gold has been dissolved in the cyanide, and the ore body has been reasonably depleted of its gold, there are two main processes for recovering the gold from the pregnant cyanide solution. One is the Merrill-Crowe zinc precipitation process and the other is the adsorption of the gold .
