A slurry is a mixture of solids and fluid that is highly mobile under gravitational and low magnitude stresses, and remains coherent (no bulk phase separation) during transport. In geophysical settings, a slurry is part of a spectrum of mass-flow phenomena known as sediment gravity flows. In agricultural, industrial, and engineering settings, a slurry is a coherent two-phase mixture …

Sedimentation is the process by which sediments are carried by water currents to areas known as sedimentary basins, such as rivers, reservoirs, lakes and canals, which allow these particles to be placed in place, altering the way areas look.

In gravity concentration, a particle experiences gravitational force, according to its size, density, and buoyancy force due to the surrounding medium. However, in the case of enhanced gravity concentration, additional forces viz. drag force, centrifugal force, and Bagnold forces act on the par-ticle, besides the gravitational force (Fig. 2).

In density-based concentration techniques, the separation process occurs by the relative movement of mineral particles due to different forces, including gravity and one or more other forces. The latter is usually resistant to the movement of particles and is provided by a fluid medium, namely air or water [6]. For an effective separation, there must be a significant …
