Spiral concentrator is a gravity separation equipment, consisting of a spiral channel connected to a vertical support. Separation of particles in spirals is based on particle size and density and the combined effect of gravitational forces, centrifugal forces, drag, and Bagnold forces (forces related to Newtonian fluid) on the particles [1,2,3].As …

Its most primitive separation processes, which probably date back as far as 4000 BC, appeared as soon as selective mining and handpicking were no longer enough to produce the desired concentration quality. Gravity concentration is at present the main concentration process in the mineral industry in terms of tons processed.
