The number of crushing steps necessary to reduce ore to the proper size vary with the type of ore. Hard ores, including some copper, gold, iron, and molybdenum ores, may require as much as a tertiary crushing. Softer ores, such as some uranium, bauxite, and titanium/zirconium ores, require little or no crushing.

We can get aluminum from bauxite beneficiation process, and the elements of residues in the process are iron oxide (10 – 30%), titanium dioxide (2 – 15%), silicon oxide (5 – 20%), and insoluble oxidation aluminum (0-20%).. These elements are difficult to completely eradicate from the residue, so it has caused a series of ecological problems.
