Therefore to leach the gold out of the ore and into solution, cyanide, and oxygen must be added to the slurry. Lime is added to the grinding circuit to modify the pH of the slurry to prevent the formation of deadly hydrogen cyanide gas. Cyanide is added in liquid form to the tanks and lime is added to the ore prior to milling.

Milling of Amenable Gold Ores | SpringerLink

Abstract. The objective of milling gold ores is to extract the gold for the highest financial return. To recover the maximum amount of gold, the ore must be finely ground in order to liberate the gold particles for gravity separation and/or chemical extraction.

GRAVITY CONCENTRATION OF GOLD FROM CYCLONE FEED IN GRINDING

Gold was subjected to the gravity concentration device in its coarsest state, i.e., as soon as a particle was discharged from the mill it saw the gravity concentration device. There were also some disadvantages: The gravity circuit had to process 3 or 4 times the new feed rate to the mill (the entire circulating load).

GRAVITY CONCENTRATION OF GOLD FROM CYCLONE

Where there is gravity recoverable gold, it is important that it be maximized, as the unit operating cost for a gravity circuit is much lower than that for any other process. Minimizing the Size of the Gravity Concentration Circuit Many process engineers view gravity concentration in gold grinding circuits as a nuisance and a security risk.
