Each mineral has different liberation size according to petrographical and mineralogical features. The mineral has to classify with a selected size in this way density differences between the wall rock and main mineral have to be minumum 20 percent in order to get maximum enrichment process. The number of screening machines and size of screening range can fix on according to types of mettarials and liberation size of minerals.
Special models of V.C.R screening machines that design for enrichment process sieve minerals 1mm to 45 micron. As result of this process, maximum density difference can be occured between the wall rock and main mineral. The mineral which has density difference is fed special enrichment desk. As a result of this process,
Non chemical enrichment process is done.
