Abstract
In this study, the refractory behavior of Kaletas ore was investigated within a diagnostic approach Pretreatment of the ore via roasting and ultrafine grinding prior to cyanide leaching was also examined to enhance the gold recoveries No significant improvement in the extraction of gold by roasting of the ore at 450 600 °C was observed despite the decrease in the cyanide consumption Two-stage cyamdation of ultrafinely ground ore was found to improve the extraction of gold to 93% with the implication of presence of readily recoverable gold and slowly dissolving gold in the ore Diagnostic leaching provided an insight into the refractoriness of the ore, which could be attributed to the very fine gold particles locked up largely within the carbonates, oxides and sulfides and, to a small extent, within silicates present in the ore matrix
