same ore for 264 hours. The Au extraction profile was highly reproducible up to 144 hours in the second test, where Au extraction was % after 96 hours at kg/tonne ore NaCN consumption. After 96 hours, the % Au extracted tended to decrease.
metal ores (<1% copper, <1g/ton gold, < % nickel) previously considered uneconomical, became feasible with introduction of heap leaching technologies (Marsden, 2009). In consideration of ore types, a generalized diagram showing the applicable ore beneficiation technologies for oxide and sulphide ores versus ore grade is given in Figure 2.
Gold is processed by cyanide milling, a chemical procedure that separates 95 to 98 percent of the gold from raw mined ore. It is then refined to the gold standard purity, according to Mineweb. Heap leaching is a less expensive method of gold extraction, but it is a longer process and it recovers less gold than the cyanide milling process.
