Dynamic simulation of the carbon-in-pulp and carbon

In the carbon-in-pulp process adsorption occurs after the leaching cascade section of the plant, and in the carbon-in-leach process leaching and adsorption occur simultaneously. In both processes the activated carbon is moved from one tank to another in countercurrent with the ore pulp until the recovery of the loaded carbon in the first tank.

Treatment of carbonaceous refractory gold ores -

1991-1-1  One solution was to increase the amount of activated carbon in the circuit and revert to countercurrent use of the carbon. Two new autoclave plants are due for commissioning within a year. They are those for METBA's Olympias mine in northern Greece, due in the fall of 1990, and Porgera Joint Venture in Papua New Guinea, due in October 1991.

guinea gold ore leaching process on sale

Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carboninpulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon. Read More
