Copper extraction - Wikipedia

A key objective in the metallurgical treatment of any ore is the separation of ore minerals from gangue minerals within the rock. The first stage of any process within a metallurgical treatment circuit is accurate grinding or comminution where the rock is crushed to produce small particles 100 μm consisting of individual mineral phases.

All the ores are also minerals but all minerals cannot be ores. i.e. both clayAl 2 O 3.2SiO 2.2H 2 O and bauxite Al 2 O 3. 2H 2 O are minerals of aluminium. It is bauxite that is used for extraction of aluminium and not clay. In short bauxite is an ore of aluminium.These ores can be divided into four groups. 1.
