In numerous cases, Ultrafine mill is most beneficial to recover the gold as a from the concentrate, and either send this item to a smelter or amalgamate or cyanide the assembles at the mine.Where the completed item does not need to be uniform, a ball plant might be worked in open circuit, however where the completed item should be uniform it is basic that the grinding mill be utilized as a part of shut circuit with a screen, if a coarse item is wanted, and with a classifier if a fine item is required. 

The particles are currently concentrated by density and can be extricated from the Jig bed independently. In the mining of most substantial minerals, the denser material would be the coveted mineral and the rest would be disposed of as floats (or tailings).There are a few minerals, remarkably coal, that are lighter (bring down in thickness) than the encompassing rock and in such cases the procedure of extraction would work backward, i.e. the coal would settle on top with the stone underneath (on the jig bed). There are a few plans and techniques for extraction from the jig bed.
