During separation, the slurry enters the spiral through a feed box and then flows on to the spiral surface. As the slurry travels down the spiral, mineral grains settle and sort according to size, shape, and specific gravity. Spiral separation uses a flowing film principle based on the size and specific gravity difference present … See more This type of spiral is used in most applications, particularly for concentrating low-grade ores. The only water required is added with the solids prior to introducing feed onto the spiral. … See more A gravity feed slurry distributor, mounted centrally on top of the spiral module, ensures even distribution of feed to each spiral start. The … See more Washwater spirals require the addition of water at various points down the spiral providing more efficient washing of the concentrate, i.e., transporting away light gangue (silica) from the concentrate band. See more WebFeb 8, 2024 · In spiral separators, the separation of heavy and light minerals takes place in streaming currents. The equilibrium between the centrifugal force outwards and the gravitational force downwards facilitates the separation of particles based on their density and size. ...
