Insufficient slurry handling may result in bringing the whole plant to a halt or leading to inefficiencies in important processes such as grinding, classifiion, separation, dewatering, and tailings handling. offers complete solutions for slurry handling including equipment, parts, as well as
Read MoreThis process is very similar to the CIP process. The main differences lie in the preparation of the slurry and method for removing the gold from the leachate. In a CIL process, the carbon is mixed with the leachate solution, not with pulp. This is a much less abrasive system meaning that the carbon lasts much longer than in a CIP process.
