Strong magnetic particles may be easily separated with a separator having a low intensity magnetic field of 400 600 gauss. Paramagnetic particles (weakly magnetic) require a higher intensity magnetic field to separate them, generally ranging from 6,000 to 20,000 gauss. Particles that are repulsed by a magnetic field are called diamagnetic.
Electromagnetic Separation of Copper Iron Sulphides
Electromagnetic Separation of Copper Carbonates. The ore contained 2.9 per cent. copper, and was passed over a HumboldtWetherill separator excited by 18 amperes at 90 volts, and repassed at 14 amperes. Of the total feed, 12.6 per cent. was recovered as a concentrate assaying 17.2 per cent. copper, and 85.4 per cent.
Smelting. Copper can be lost from the matte in three ways: as cuprous oxide (Cu 2 O) dissolved in the slag, as sulfide copper dissolved in the slag or as tiny droplets (or prills) of matte suspended in the slag. The amount of copper lost as oxide copper increases as the oxygen potential of the slag increases.
Copper beneficiation process Yantai Jinpeng Mining
Copper ore divides into ore sulfide ,ore oxide and mixing ore according to its oxide rate . The main process for copper ore is flotation , for refractory mixed copper ore and refractory oxide ore , normally use hydrometallurgy process .It is a high technological enterprise that integrated research , manufacture, sales and service .

In mining operations engineers use their knowledge of the characteristic properties of minerals to separate valuable substances from the surrounding rock. This involves a variety of physical and chemical processes.. Physical processes include sieving, sedimentation, flotation, magnetic separation, filtration, and evaporation.
