The composition and mineral relations of the clay minerals are intimately related to the conditions under which they form. In general, alkalic feldspars and the micas tend to alter to kaolin minerals, whereas ferromagnesian minerals, calcic feldspar?, and volcanic glasses commonly alter to members of the montmoril lonite group.

Mineral processing usually requires reducing the particle size of the ore, a process called comminution followed by separating ore and gangue minerals and concentrating ore minerals. The mined ore is tipped into a crusher crushing the blasted rock from the mine to smaller pieces, usually the of small stones or gravel.
