High Intensity Magnetic Separation of Scheelite

2021-3-23  At present, the coarse separation of scheelite is usually by gravity separation or flotation. Because scheelite is a kind of ore which is easy to be gravity-dressed, but because scheelite has fine dissemination size, it needs to be grinded to 0.2 mm before the basic monomer dissociation, thus increasing the difficulty of gravity recovery, and the recovery rate of gravity-dressing is low, the ...
