Bauxite is, at present, the only primary aluminium resource: 85% of the mined bauxite is refined into alumina, an intermediate product (Bayer process), which is then smelted (Hall–Heroult process) into aluminium. A total of 10% of the bauxite goes to nonmetal products and 5% to refractory and abrasive materials [2] (in [3]).
The heap leaching process involves several steps. First, a leach solution is used to irrigate the heap. The second step is interaction with the ore particles. Third, the precious metal leaches out of the solution. Fourth, the pregnant solution is collected, and finally, draining of the tailing areas is done for metal extraction.
