There are two types of centrifugal techniques for separating particles: differential centrifugation and density gradient centrifugation. Density gradient centrifugation can further be divided into rate-zonal and isopycnic centrifugation. Differential Centrifugation. Rate-Zonal Centrifugation. Isopycnic Centrifugation.

of the particles affect the relative movement and hence the separation. The ease or difficulty of separation depends upon the relative differences in these factors. The 'Concentration Criteria' (CC) which gives an idea of the amenability of separation of two minerals, can be expressed by (dH - dF) CC=(dL-dF) where dH = sp. gr. of the heavy mineral

The principle of gold concentration in centrifugal equipment is the separation of gold from gangue mineral particles based on the difference in the settling velocity (Chen et al., 2020) . When the particles are subjected to the normal gravitational force (G-force = 1), like in a jig, a gold particle with a diameter of 0.02 mm falling in water ...

Quartz was a major phase, with minor impurities in two different types of gold ores and their respective tailings. The beneficiation carried out using centrifugal separation, regarded as an extension of gravity separation, showed gold grades in the range of 535–1515 g t−1 for gold ores and 36–302 g t−1 for artisanal gold mine tailings.
