Leached pulp and carbon are transferred in a countercurrent flow arrangement involving a series of tanks, usually numbering 4 to 6. In the final tank, fresh or barren carbon is put in contact with low grade or tailings solution. At this tank the fresh carbon has a high affinity for gold and can remove trace amounts of gold (to levels below 0.01 mg/L Au in solution).

fresh water instead of contaminated condensates in the scrubbers and pulp washers further reduces odorous emissions. Several new mills have incorporated recovery systems that eliminate the conventional direct-contact evaporators. In one system, heated combustion air, rather than fuel gas, provides direct-contact evaporation.

The pulp and stone sector was responsible for about 190 Mt of CO 2 emissions in 2021, about 2% of all emissions from industry and a historic high. As stone production is projected to increase to 2030, significant efforts must be made to reduce the emissions intensity of production. This can be accomplished primarily by moving away from fossil

Carbon in pulp process. Gold Carbon-in-pulp (CIP) production 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.
