Spirals in Australia mineral processing

The specific gravity of a mineral is the ratio of its density to that of water. For example, gold has a specific gravity of 19.3, which is 19.3 times denser than water. This high density facilitates separation from other minerals by gravity concentration techniques. Gravity concentration is best for coarse particles as they settle faster than ...

How gravity concentration recovers ultra-fine particles

where g is the gravitational acceleration (m/s2), R is the radius of the spherical particle, Ï p is the mass density of the particles (kg/m3), Ï f is the mass density of the fluid (kg/m3), and μ is the dynamic viscosity (kg/m*s). From these equations we can understand that the settling velocity decreases by the square of the particle size.
