potash ore sylvinite

Document

When potash occurs, it often overlies the halite to form the top of the cycle, or it may be interbedded within the halite. Each cycle is marked, top and bottom, by sharp contacts interpreted as disconformities. The potash-bearing ore, sylvinite, is a mixture of sylvite or potassium chloride (KCl) and halite or sodium chloride (NaCl).

fine size and screened to get only the ore of required size. Solutioning The ore is dissolved in hot water and to that is added the NaCl solution (brine) for obtaining a mixture of KCl + NaCl. The temperature of the mixture is increased by which more and more of sylvinite will dissolve and the solubility of NaCl will stop after a stage.

Sylvite: The potash mineral sylvite information and pictures

Sylvite is an economically important mineral and is extensively mined, though it is rarely represented in mineral collections as attractive specimens.
