Mining
For iron ore this involves crushing the ore and then concentrating it in different ways, for example by milling, flotation or magnetic separation. At some sites the ore is processed further and pelletised for use in direct reduced iron (DRI) steelmaking. In the processing stage, the mined material is transformed into usable raw material.

Minerals | Free Full-Text | Production of a Phosphate
The removal of fines in apatite ore processing is a standard procedure [1,2,3,4,5,9] as fines consume reagents and cause a loss of selectivity during the subsequent flotation step used to concentrate apatite. The desliming of the CC has been assessed with the dry sub-sample (see Figure 2) using a hydrocyclone and a spiral …

One such example is the iron ore sector, which involves separating large amounts of valuable iron minerals from gangue minerals. Plants processing those minerals treat many millions tons of ore every year, and most of the refinement and separation techniques used rely on bulk ore properties (density, size, magnetism) and wet processing.
