Critical copper concentration in sphalerite flotation: Effect
1 Introduction Sphalerite is a valuable mineral for zinc and has been one of the most studied sulphide minerals in relation to its flotation (Finkelstein and Allison, 1976, Finkelstein, 1997)Recovery of sphalerite from ores is quite a complex process; generally its flotation needs to be first depressed in copper and lead circuit at neutral to mildly alkaline pH values before it R Dunne, in Gold Ore Processing (Second Edition), 2016 75 Flotation of Copper–Gold Ores For the bulk flotation of copper minerals and gold from supergene copper ores, it is normal practice to add a xanthate as the primary collector and dithiophosphate as a secondary collector (Bulatovic, 1997) This combination gives satisfactory results Copper Ore an overview ScienceDirect Topics The DC current drives the copper plating process containing industrial copper concentrations, to study the copper reduction reaction with the aid of common electrorefining additives The presence of a mid frequency capacitance as part of a twostep electrode reaction, which previously was assumed to be present, could be visualized and The timevarying effect of thiourea on the copper Copper concentration process Large amounts of water are used in the copper concentration process, although disposal of liquid wastes is rarely a problem because the vast majority of the water is recycled back into the process Once the wastewater exits the flotation process it is sent to a sediment control pond where it is held long enough for most of the sediment to settleCopper concentration process Big Chemical Encyclopedia4 Beneficiation of Copper Ore The next step in processing is called beneficiation This is the first step in concentrating the copper into a more useable form 5 Smelting and Extraction The next step in the process flow is smelting for sulfide ore concentrate and solvent extraction for oxide ore leach solution 6From Ore to Finished Product Copper
