用普通方法从脉石矿物中分选硫化矿物,不仅要消耗大量工时,而且药剂、电力和水的消耗也很大、比较经济可取的方法是用金属化合物与硫化矿接触,使其在硫化物颗粒表面发生反应,而不与脉石颗粒反应,从而在改变金属硫化物表面特性的条件下,有选择地增大硫化矿物的磁导率。通过磁选使硫化物有用成分与脉石分离。铁的无机和有机化合物都能增大金属硫化物的磁导率。例如:氯化亚铁、氯化铁,
The conventional method of sorting sulphide minerals from gangue minerals not only consumes a large number of working hours, but also consumes large quantities of chemicals, electricity and water. A more economically preferable method is to contact the sulphide metal with a metal compound, The particle surface reacts without reacting with the gangue particles, thereby selectively increasing the permeability of the sulphide mineral under conditions that alter the surface properties of the metal sulphide. By magnetic separation so sulfide useful components and gangue separation. Iron inorganic and organic compounds can increase the permeability of metal sulfides. For example: ferrous chloride, ferric chloride,
