In addition, whereas the mill will be primarily run from local start/stop stations, the crusher is designed to be run from its control panel. The dividing point between the two plants lies at the fine ore bin; all equipment prior to this bin is considered in the Crushing Plant and all equipment subsequent to it in the mill. General Design Criteria:
Carbon-in-pulp (CIP) is the sequential leach then absorption of gold from ore. During the CIP stage, pulp flows through several agitated tanks where sodium cyanide and oxygen have been added to dissolve gold into solution. ... Design Criteria . In the carbon-in-pulp process activated carbon is mixed with a ground ore plus water slurry in which ...
