复合分选方法,是采用几种场配合,分选出一种或几种产物的方法。随着矿产需求量的不断增加,高品位、易分选的富矿石越来越少。因此不得不提出利用贫、细、杂矿产资源以及废料的再资源化的课题。由此产生的问题是采用常规的单一场的分选方法,难以达到较好的分选效果。近些年来,在科学实验和生产实践中,出现了复合场分选的方法,收到了很好的效果。例如在离心选矿中,应用了离心力场—重力场组合;在磁流体静力分选中,应用了磁场—重力
Composite sorting method is the use of several fields with the separation of one or several products. With the increasing demand for minerals, high-grade, easy sorting fewer and fewer rich ore. So I have to put forward the use of poor, fine, miscellaneous mineral resources and waste recycling issues. The resulting problem is the use of conventional single-field sorting method, it is difficult to achieve better sorting results. In recent years, in the field of scientific experiments and production practices, there has been a method of sorting out complex fields and receiving good results. For example, in centrifugal beneficiation, the centrifugal field - gravity field combination is applied; in the magnetic hydrostatic separation, the magnetic field - gravity
