Mineralogical and metallurgical study of supergene ores of

This study evaluates the possibilities for economic recovery by 1) comparing the Cu and Au extraction achieved from the supergene ores by six different lixiviants, and 2) identifying which minerals cause low recovery for each lixiviant and why. Gold is present as auricupride and electrum and copper exists as conichalcite (CaCu arsenate
