Dec 05, 2006 in 1952, technology was developed to strip gold from granular activated carbon and allow the carbon to be reused. in 1969, the heap leaching concept was applied to low-grade gold and silver ores and mine wastes. heap leaching in conjunction with carbon adsorption-desorption permits very low value material to be economically processed.
With ores of higher gold content i.e., greater than 20 grams of gold per ton of ore, cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent for several hours in large tanks equipped with agitators. for extracting gold from low-grade ores, heap leaching is practiced.
