Beneficiation methods are mainly divided into two categories , namely physical beneficiation and chemical processing , which includes magnetic separation physical beneficiation , gravity separation , electrostatic beneficiation method, friction beneficiation method , particle size beneficiation method , shape beneficiation method, hand-selected method. Chemical processing including flotation , roasting , leaching method.Magnetic beneficiation project for the main sorting methods , their use is different magnetic minerals . Currently accepted that strong magnetic weak , weak magnetic intensity , through multi-stage selection, to elect the final concentrate.
Divided into dry and wet magnetic separation option selected for different mineral composition , use of different processing methods . Dry them the main problems currently facing the spread of dust problem, how to effectively prevent the spread of mineral dust , neither pollute the environment , and can ensure the production of the health of workers . Wet election is now better downstream magnetic separator , it not only has good taste concentrates , while also maintaining a high recovery rate . Of course, magnetic separator used in coal preparation plant proposed multi- use counter-flow separator, counterflow is a magnetic separator to ensure recovery , preparation plant requirement is to recover heavy media , it requires recovery , counterflow more appropriate.
