GOLD RECOVERY OF REFRACTORY SULFIDE

The problem of refractory sulfide gold ore that has a gold recovery less than 50% when direct cyanidation applied, still exists until now. It needs oxidative pretreatment for cyanidation to be effective in gold recovery the objective of this study is figuring out the effect of sodium nitrite as an oxidizing reagent on cyanidation of refractory gold ore.

To recover gold from sulfide concentrates, roasting or oxidation can be performed first, followed by cyanide leaching. Direct cyanidation of flotation concentrate can often encounter problems. Numerous methods are available for oxidizing flotation concentrates, including biological oxidation, pressure oxidation in autoclaves, roasting, as well as proprietary processes, such as Albion and Leachox.
