Gold CIL & CIP Gold Leaching Process Explained

Gold CIL & CIP Gold Leaching Process Explained

the barren pulp is disposed of as tailings and the precious metals are recovered from the strip solution by electrowinning or zinc precipitation. the carbon-in-pulp process is used to treat low grade gold and/or silver ores. the ore is first ground in a ball mill which operates in closed circuit with a cyclone or similar sizing device.

overall, the general advantages and disadvantages of the ion exchange process for the recovery of cyanide and metal can be listed as follows (gilmore, 1976): advantages: (1) reduces cyanide and heavy metals to 0.1 mg/l total cyanide and 0.3 mg/l cu, 0.5 mg/l ni and 0.5 mg/l zn. (2) recovers and conserves the cyanide and metals for reuse. (3)

Sorting through the heap - Canadian Mining Journal

Sorting Through The Heap - Canadian Mining Journal

one of the advantages of heap leaching versus conventional milling and using either carbon-in-pulp (cip) or carbon-in-leach (cil) for gold recovery is the lower cost. however, along with that lower cost comes a lower recovery rate. gold recovery is also usually only about 55% to 75% compared with roughly 90% recovery in an agitated leach plant.
