Research on Mineral Processing Technology of Complex and Difficult Sulfide Copper Mine Selection
When mining sulfide copper ore,it is often faced with complex mineral properties and high oxidation rates.Copper and sulfur minerals are densely embedded and have characteristics such as fine embedded particle size,severe mud formation,and multiple clay minerals.Therefore,it is necessary to upgrade the beneficiation process.Based on the properties of sulfide copper ore,BK404 collector was selected for copper mineral collection,and a combination of lime and BD was selected to suppress pyrite and gangue ore.Utilize processes such as priority copper flotation,coarse concentrate re grinding,and selection for copper mineral recovery.After the process optimization the copper concentrate after beneficiation has a copper content of 20.13%and a copper recovery rate of 74.48%.The beneficiation effect is obvious,and it can efficiently recover complex and difficult sulfide copper ores selection.The optimization value of the beneficiation process is high.
