Auriferous Deposits

 · The problem is the high content of arsenic. If the mineral is refractory to cyanidation, the problem is more serious. If the ore body has pyrrhotite, the cyanidation process can be problematic due to this iron sulphide mineral takes very easy the oxygen from the environment. The leaching process is not efficient even at cyanide consumptions.
