Abstract
The direct cyanide leaching rate of gold from a gold calcine was only 71.33%, due to 19.51% of gold being encapsulated in the iron oxides. To enhance the cyanide leaching of gold, the calcine was pretreated with acid or alkali washing. The mechanisms by which acid and alkali pretreatment improve gold leaching from calcine are investigated through chemical analysis, XRD, and SEM-EDS characterization.
