A recent review Kappes, 1998 concluded that for a typical Nevada-type ore body with ore grade of 3.0 grams goldtonne 0.088 ozton, the mill recovery would have to be 21 higher than the heap leach recovery to achieve the same return on investment - and this is very seldom the case.
May 19, 2009 Each ton of ore that is hauled out of a good pit mine may contain about a tenth of an ounce of gold. With gold at, say, 900 an ounce, that makes a ton of ore worth 90, tops.

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.

More gold is recovered by cyanidation than by any other process. In cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content greater than 20 grams of gold per tonne of ore, cyanidation is accomplished by vat leaching, which involves holding a slurry of ore
