Gravity-concentration processes exploit differences in density to separate ore minerals from gangue. Selection of a particular gravity-based process for a given ore will be strongly influenced by the size to which the ore must be crushed or ground to separate values from gangue, as well as by the density difference and other factors.

Magnetic Separation

Magnetic separation is applied in the ore milling industry, especially the beneficiating ores of iron, columbium and tantalum, and tungsten, both for extraction of values from ore and for separation of different valuable minerals recovered from complex ores. Separation is based on differences in magnetic permeability (which, although small, is measurable for almost all materials) and is effective in handling materials not normally considered magnetic.

Electrostatic Separation

Electrostatic separation is used to separate minerals on the basis of their conductivity. This process is inherently dry and uses very high voltages. In a typical application, ore is charged at 20,000 to 40,000 volts, and the charged particles are dropped onto a conductive rotating drum.

Flotation

Flotation is a process by which the addition of chemicals to a crushed ore-water slurry causes particles of one mineral or group of minerals to adhere to air bubbles. When air is forced through the slurry, the rising bubbles carry with them the particles of the mineral(s) to be separated from the matrix.

Ore separation is a relatively complicated operation. It involves many different techniques, such as milling (crushing and grinding); washing; filtration; sorting; sizing; gravity concentration; magnetic separation; flotation etc.
