Almost of mined iron ore is used in steel production, making it essential for everything from staples to buildings. Beneficiation is the term for reducing the size of valuable iron ore particles and separating them from the gange (unusable minerals), which are then discarded. There are several different methods of wet and dry separation.

The conventional phosphate beneficiation process. As mined, the phosphate and sand particles are embedded in compacted mud, or "clay-balls". Before separation can begin, all the particles must be liberated from the matrix of mud. The very first unit operation in the beneficiation process is to disaggregate the various particles; this ...
