Mineral Separation | Iluka Virtual Mine Site Tour

In terms of mineral separation plants, the engine room is the electrostatics. The technology for separation is primarily electrostatic separation: separation based on the conductivity differential between the minerals. Circuit configurations can be quite variable and depend upon the heavily mineral assemblage of the feedstock.

Particle Size Analysis for Mining and Minerals ...

In many cases, the valuable minerals are mixed with gangue, commercially useless material, and the ore must be separated. The first step of many separation processes is comminution (size reduction) followed by classification (separation by particle size) either for further grinding or the next step, concentration of the ore.

How do you separate a mineral from a rock?

Separating rock and mineral That depends on what kind of mineral and what kind of rock. If there is a difference between the density, i.e. the weight, of the mineral and rock, then you finely crush the rock and use 'flotation'.

TIMS - Department of Earth and Planetary Sciences

Density Separation. Density separation is based on the fact that different minerals have different densities. Thus, if a mixture of minerals with different densities can be placed in a liquid with an intermediate density, the grains with densities less than that of the liquid will float and grains with densities greater than the liquid will sink.
