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 ...
