1.General Introduction
The spiral chute is a kind of gravity beneficiation equipment which sorts the ore particles according to density, particle size and shape by the interaction of centrifugal force, groove surface friction force, water flow pressure and mineral gravity. From the flow direction of the slurry in the tank, in addition to the primary circulation flowing in the longitudinal direction of the tank, there is a lateral exchange between the inner edge fluid and the outer edge fluid, which is called a secondary circulation. The secondary circulation can push the gangue light mineral suspended on the neutral surface to the outer edge and become the tailings. In the process of the slurry flowing downward along the groove, the minerals of different densities and different particle sizes gradually move on a specific orbit according to their own characteristics under the combined action of various forces. The general trend is that the gangue tends to the outer edge, and the fine and heavy minerals tend to the inner edge. When one of the ore particles receives a radial component of zero, the ore does not move toward the inner edge, nor moves to the outer edge, and only rotates around the central axis of the spiral at a certain position in the chute.
