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.

A new method for gravity separation: Vibrating table gravity
All desulphurised materials from gravity and flotation methods were in the non-acid generating zone. The gravity method offered a sulphur recovery of about 84 wt%. The pyroanalysis of gold (Au) and silver (Ag) on the concentrate of desulphurisation with gravity methods display a gold content of 3,78 g/t and of 4,9 g/t for silver.

Gravity Concentration Methods
Gravity Concentration — the separation of minerals by virtue of specific gravity — is one of the oldest forms of mineral processing. Whilst its relative importance has declined in the twentieth century, the high cost of alternative processes, along with the development of a range of high capacity devices has led to something of a renaissance of gravity concentration.
