In the carbon leaching method and the chemical beneficiation leaching solution treatment, the slag leaching and adsorption of the slurry adsorption process are simultaneously carried out by using activated carbon. It was the early 1980s, South Africa Ming Teke (Mintek) concentrator successfully developed on the basis of carbon paddles on the gold extraction process.
The cyanide leaching time in the cyanide carbon slurry process is much longer than that of the dissolved gold. It is necessary to prepare two sets of equipment for leaching and adsorption. Therefore, the capital investment of the carbon slurry process is high, the plant area is large, and the process is retained. The amount of gold and silver is large, and the backlog of funds is serious.
The carbon leaching method, while leaching and absorbing, overcomes the above disadvantages of the carbon slurry method. The carbon leaching process is generally carried out in 5 to 9 leaching adsorption tanks, and the activated carbon in the system flows countercurrently with the slurry through the inter-tank screen. The preparation of raw materials for charcoal leaching, desorption of gold-loaded charcoal, regeneration of charcoal, treatment of noble liquid and tailings are the same as those of carbon slurry. Compared with the carbon slurry method, the capital investment of carbon leaching method is small, the plant area is small, and the amount of gold and silver retained in the process is low, but the wear of activated carbon is serious, and the gold and silver in the tail slurry are lost with the wear of particulate carbon. The amount is higher than the carbon slurry method.
