Tailings mineral concentration
Concentration of Minerals Article about Concentration of
The results of mineral concentration are two main products: the concentrate and tailings. In some cases (for example, in the concentration of asbestos or anthracite), the concentrates differ from the tailings mainly in the size of mineral particles. If an ore contains several useful components, several concentrates are produced from it.

Tailingsfo Thickened Tailings Storage - A discussion
Increasing the thickness of the tailings pulp (i.e. increasing the %solid concentration) creates higher beach slopes angles in comparison to tailings discharged with a higher content of water (i.e. lower %solid concentration). The tailings are generally discharged from topographical high points within the tailings storage facility or by riser

Most mineral deposits are composed of many different minerals, some of which contain metals. A mineral deposit may be the host to more than one metal but not all metals may exist in sufficient quantities to be of economic interest.
