CIP and CIL | Mining and Minerals | Industries | Lightnin | SPX

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. In the absorption stage, this solution flows through several agitated tanks containing activated.

These stellar attributes of the carbon-based gold plants have led to complacency and laziness in the. industry, both at the new plant.

15.11 Gold leaching

for small percolation-leaching plants only minimal costs for the masonry construction of leaching basins, precipitating basins and leach collection containers, totalling approx. 1000 DM depending upon cost of materials. For industrial-scale plants, (e.g. CIP - carbon-in pulp process) costs are extremely high at 1.000.000 DM.

The Metallurgy of Cyanide Gold Leaching – An Introduction

Oct 20, 2014 . In a typical application, a slurry of the ground ore is mixed with cyanide in the presence of activated carbon. The carbon has a very high affinity for the aurocyanide complex and adsorbs the gold out of solution resulting in very high loadings on the carbon (typically 1000-4000 g/t). At the end of the leach the.
