Gravity Separation - an overview ScienceDirect

Gravity separation has been applied to process chrome slag by steel researchers in India. Heavy media separation (Choudhury et al., 1996) and crushing and jigging (Khan et al., 2001) are the principal techniques used. The slag is subjected to 2-stage crushing to reduce the size to −10 mm and then screened into −10 +1 mm and −1 mm fractions.

Spiral Concentrators — IMSC Group

Spiral separation is based on the specific gravity difference present in a feed mineral suite. When fed a dilute pulp mixture of minerals of different specific gravities, the lighter minerals are more readily suspended by the water and attain relatively high tangential velocities so that they climb toward the outer rim of the spiral trough.

Gravity separation - Wikipedia

Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.

Choosing The Correct Gravity Separation Machine

Gravity Separation For Medium-Sized Particles Spiral Concentrators. Spiral concentrators are towers that resemble miniature waterslides. A slurry composed of similarly sized particles is fed to the top of the spiral concentrator. As the slurry flows down, denser particles move closer to the centre of the spiral, and lighter particles are pushed outwards.
