ContactEffective flotation collector reagent selection is dependent on the sulphide minerals present, their mineral associations in the ore, and circuit characteristics. Because an ore typically has more than one copper sulphide mineral type, often a combination of sulphide flotation collectors is used to maximize metallurgical performance.
Contact2010-12-16 The chalcocite and primary ores can be treated for sulphide concentrate recovery using standard copper flotation processing technology. Once the coarse native copper has been recovered from the native copper ore, it is then also able to be treated through the same circuit used for treating the chalcocite and primary ores.
