Oxide Copper Leach ModelingThe leaching and adsorption behaviour of gold ores

The model is based upon the hypothesis that extraction is directly proportional to the volume of a piece of ore that is penetrated by the leaching agent and that each piece of ore regardless of size has been penetrated radially from external surface to the same depth at a given leaching time The modeling of leach dumps and in situ systems of low grade copper sulfides has received much Kinetic models were developed for the leaching of gold from the ore adsorption onto activated carbon and preg robbing at the ore surface A variable order empirical
