Processing of potash ore Беларуськалий

The potash ores are the main raw material used to produce potash and compound fertilizers and other chemicals. The potash ore generally consists of sylvite (KCl), halite (NaCl – the rock forming mineral) containing the inclusions of carnalite, anhydrite and silicate and carbonate (insoluble residue).

Potash minerals

Potash deposits free of, or poor in, MgSO 4 minerals are dominated by some combination of halite, carnallite, and sylvite and typify much of the Phanerozoic rock record. This MgSO4depleted group constitutes the majority of known reserves of exploited potash, which are dominated by Devonian evaporites in Canada.
