gravity gold separation view gravity gold

Processes - Gekko Systems

The gravity concentration separation process gets more complex as the specific gravities between the valuable mineral and the gangue get closer. For example, complex gold in a sulphide complex of pyrite, must isolate a specific gravity of 19.3 for gold from 5.2 for pyrite. Using gravity to recover minerals in their coarsest fraction minimises ...

The gravity field is reassuringly simple, unipolar and almost perfectly vertical. The common unit of gravity measurement in exploration geophysics is milliGal (1,000 mGal = 1 Gal = 1 cm/s 2 = 0.01 m/s 2 ). These units refer to acceleration due to gravity, and the average value at the earth surface is around 980,000 mGal or 9.8 m/s 2.
