Under the solution mining method of the sylvinite member, MOP is produced from the brine received by solution mining of a sylvinite deposit. MOP production from conventional mining of a sylvinite deposit includes mechanical separation and hot leaching of the ore to form a KCI liquor that is further crystallised.

The modern processing of sylvinite and other potash ores is usually a comparatively simple and standardized procedure, practiced in much the same way at most potash plants. In the early days of the industry, and still with some operations having complex ores or to process fines or waste streams, the ore was given a hot leach, the undissolved salt and insolubles rejected, and the clarified

The high grade of sylvinite obtained from deposits in Saskatchewan (about 40% KCl; n about 2) favored the application of the differential surface activity between the finely ground potassium and sodium chlorides present to effect a separation of the two minerals, rather than the considerably more energyintensive solution of using fractional crystallization technology [14, 29].

Potash Minerals will also be able to take advantage of the fact that their deposit is sylvinite, which is the more desirable type of mineralization for potash in North America. Because sylvinite is easier to process, it will ensure the delivery of a higher quality potash that ultimately helps to offset costs often associated with other potash deposits, which require more processing to

It is an inexpensive bulk mineral also known as halite which can be found in concave rocks of coastal areas or in lagoons where sea water gets trapped and deposits salt as it evaporates in the sun. The most important salt minerals, which produced by solution mining are: Rock salt (or Halite) (NaCl) Sylvinite (NaCl + KCl) Carnallite (KMgCl3*6H2O or MgCl2 * KCl * 6H2O) Trona
