Agitated Copper Leaching Cementation Process

The agitated leaching method is limited to those ores, or to that portion of those ores, that because of particle size do not permit free passage of leach solution through the interstices between the ore particles and. thus, cannot be effectively treated by heap or vat leaching.

Bioleaching

Bioleaching is the extraction of metals from their ores through the use of living organisms.This is much cleaner than the traditional heap leaching using cyanide. Bioleaching is one of several applications within biohydrometallurgy and several methods are used to recover copper, zinc, lead, arsenic, antimony, nickel, molybdenum, gold, silver, and cobalt.
