Innovative technology has been successfully applied to the preferential solution mining of potassium chloride from the sylvinite deposits 215 m thick and lying some 1600 m below the surface situated under much of southern Saskatchewan. These beds would at best be only marginally profitable to mine by conventional means. This unique operation takes advantage of the differential, which exists ...

In some areas, sylvinite deposits rich in potassium chloride are found at depths of from about 4,000 to about 6,000 feet. Since dry mining these sylvinite deposits is prohibited by economic and safety considerations, solution mining of the deposits has heretofore been proposed and utilized.

The second option SolMin2 is characterized by the selective solution mining of units in areas where Bischofite exceeds a certain thickness. In this case, solution mining takes place initially in the lower horizons, finally followed by the upper horizons after piping is drawn to the upper Carnallite and Sylvinite

With solution mining, a brine is heated and injected into the deposit to dissolves the potash. The potash-rich brine is then pumped out of the cavern to the surface where the water is evaporated. Solution mining involves dissolution of the potash with water. Wells are drilled into the potash-bearing area (sylvinite bed) and water, later brine ...

Heretofore it has been generally conceded by those skilled in the art of solution mining of sylvinite deposits that only thick beds, in essentially flat deposits, could be solution mined economically. In prior solution mining, an oil blanket, air blanket or some other such material had to be maintained on the top of the solution mining liquid ...

More specifically, the invention relates to selective solution mining generally horizontal beds of sylvinite, i.e., a mixture of crystals of halite (NaCl) and sylvite (KCl) wherein water or salt brine is washed down a generally vertical bore hole into the deposits and recovered enriched with dissolved KCl.

Solution mining techniques, focused on caverns in halite, are discussed in detail in Chapter 13, Warren (2016). Solution mining can substitute for conventional shaft mining in some potash deposits at depths of more than 1,100m, which is the current limit for conventional potash mining.

Ancient marine-type potash deposits that are close to the surface can be mined using conventional underground mining methods. In situ solution mining can be used where beds are too deep, making underground mining cost-prohibitive, or where underground mines are converted to in situ solution mines. Quaternary brine is another source of potash ...

In three drill holes (DX_10, DX_12 and DX_15B) well developed sylvinite was intersected in the Top Seams and sylvinite overlying carnallite or simply carnallite was intersected in the underlying Hangingwall Seam. The presence of carnallite within the seams effectively excludes that area from solution mining to recover sylvinite.

Jul 06, 2016 Conventional Solution mining of sylvinite for potash is performed as primary mining, wherein the well injector fluid is almost pure water. This allows for a large KCl concentration difference and a reduced circulation rate, but due to a greater solubility for NaCl than KCl, more NaCl is mined than KCl, as shown graphically in FIG. 6 .

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 ...

Primary mining will progress in successive mining cuts, with occasional additions of oil to maintain the oil blanket. Each mining cut will be approximately 1 to 1.5 m thick. When a lift has been completed, the casing is perforated and the new section of the potash deposit is solution mined.

The relatively shallow and high grade nature of the Sylvinite Zone make this area ideal for solution mining with recovery through solar evaporation.
