The high oxidizing potentials involved with some lixiviants lead to high reagent consumptions due to reaction with sulfide minerals contained in the ore and the oxidation of the reagent itself. A point to consider is that the adsorption of reagents and/or precipitation of gold onto some gangue minerals that can affect the overall gold recovery.

treatment of transition or sulphidic ores gave poor gold recovery and required higher reagent concentrations (Muir, 2011). Moreover, both cyanide and ammonia have detrimental environmental effects. Muir et al. (1989) reported that there arefive methodologies for treating copper–gold ores: (1) float and produce a copper–gold con-
