Mineral mica friction coefficient of rolling friction from the difference in the coefficient of sliding friction and rounded into a sheet-like gangue mica crystals, separating the crystals of mica and gangue. One of the devices used is a swash plate sorter. The machine is composed of a group of metals consisting of the swash plate, the swash plate of each length of 1350mm, width of 1000mm, under an angle larger than the inclination of the swash plate on a swash plate. A slit for collecting mica crystals is left at the lower end of each swash plate, and the width thereof is sequentially decreased in the order of slanting plates. The front edge of the slit is equipped with a triangular raft. During the sorting process, the large gangue rolls down to the stone pile; the mica and the smaller gangue block are blocked by the raft, and the sloping plate is dropped through the gap. The above process is repeated on the swash plate in turn to gradually separate the mica from the gangue. At present, the friction beneficiation process and equipment are not perfect, so this method has not been widely used in mica ore dressing.
