Ore processing is a 24 hour operation. Ore is stockpiled at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added to raise its pH. Following crushing through a jaw crusher, the ore is fed into the semi autogenous grinding (SAG) mill along with water and steel balls.

From a lime consumption perspective, hydrometallurgical gold processing can broadly be classified using three ore features: (1) gold grade, (2) copper mineral content and (3) pyrite content, as illustrated in Table 2, with typical lime consumption ranges given as a function of ore feed (Lhoist data). The combination of these features …
If the solution is rich enough can be treated by zinc powder and the precipitated obtained (cement) obtained will be sent to retorting and smelting. For gold extraction the strength of cyanide solution ranges from 0.01 to 0.05%. Lime is added to the process in order to have a pH near to 10-11.
