1. Concentration by dense medium

The solids to be separated are immersed in a fluid with a density between that of the heavy and light products. Separation takes place according to simple Archimedean thrust or multiplied by a centrifugal force coefficient [15][32] . This thrust acts in the same way regardless of particle size. The accuracy of separation depends essentially on the qualities of the fluid and the degree of liberation achieved.

1.1 Process advantages

Flow rates can be very high. The probable deviation is usually small, and good separation can be expected with a simple density deviation Δd ⩽...
