25/04/2018· In the case of gold recovery, heap leaching generally requires 60 to 90 days to leach the ore, compared to the 24 hours required by a conventional agitated leach process. Gold recovery is also usually only 70 compared with 90 recovery in an agitated leach plant. Other metals, such as copper, use solvent extraction and electrowinning to extract the target metal from the solution. According to
18/04/2017· The cost of about 28 grammes of gold obtained by using direct cyanidation from similar ores could reach USD 800, which is economically not viable since an ounce of gold on the stock exchange is worth USD 1200, researchers said. The new technology reduced the cost of production by 30

The infrastructure for a processing plant that uses cyanidation typically costs $30 million, and is therefore, a barrier to entry for gold miners with smaller deposits that do not fit into the large scale economies of gold production. Gold recovery by cyanidation is also of environmental and safety concern as it relies on the use of toxic cyanide.
