Efficiency of operation of mining and processing, as well as metallurgical enterprises, depends on rational usage of metallurgical and processing factory wastes.

High efficiency of slag extraction from the processed material at the cost of ferromagnetic components is achieved by dry magnetic concentration. The process may consist of several separation stages:

During the first stage of magnetic separation it is necessary to extract the strong-magnetic inclusions (ferrous metals) from the product. For this purpose, pulley separators (SMB), installed instead of the conveyor's drive pulley, or suspended magnetic separators SMPR & SMPA (manual cleaning system & self-cleaning correspondingly), which are installed above the conveyor belt, 300 mm. above the product burden, can be used. One of the main advantages of the SMPR model is that those separators do not consume electric power, making the model indispensable for heavy-duty industrial tasks, where fire and explosion safety is essential.

During the second stage of magnetic separation, extraction of weak and mid-magnetic product components takes place , by processing the product on the high-power roll magnetic separator (SMVI), and modular magnetic drum (SMBM model). Material fraction size can vary from 0,1 up to 2 mm. This allows significant improving of the quality of magnetic separation.

During the third stage of magnetic separation, it is possible to extract valuable non-ferrous metals by processing the product on an eddy-current SMVT separator. SMVT magnetic separators were designed to extract ferrous (conducting) materials, varying in size from -100,0 up to +5,0 mm, such as aluminum, copper, brass, tin, etc. Separator's principle of operation is based on generating electromotive force (EMF) in conducting materials, thus providing different trajectoriesof movement for different materials, depending on their weight. Separation of metals and inert product is performed, depending on their trajectories.
