This formation and two of its four potash members extend into southwestern Manitoba, where ore grades and tonnages are comparable
Jul 01, 2011 The Upper Kama is second in size to Saskatchewan Canada Prairie Evaporite deposit among the worlds currently mined potash occurrences. Potash deposit consists of the potash-bearing beds located at the depths between 75 and 450 m Garrett, 1995. Sylvinite, as the most sylvite-rich crude ore, is mined in the Upper Kama deposit.

Potash deposit consists of the potash-bearing beds located at the depths between 75 and 450 m Garrett, 1995.Sylvinite, as the most sylvite-rich crude ore, is mined in the Upper Kama deposit. There are three distinguished types of sylvinite ore referred to as red, banded and multi-colored sylvinite, which differ in texture and sylvite content.
ABSTRACT The Esterhazy Member is the lowermost of four potash-bearing members of the Prairie Formation. It consists primarily of variable proportions of halite, sylvite and carnallite. On the basis of bromine analyses, it appears that these salts have all undergone recrystallization. Petrological investigation shows that almost all of the carnallite is younger than the halite or sylvite.
potashstratigraphic test drillholes penetrate the Prairie Evaporite, of which 30 have core through the potash beds. Additionally, there is a good cross-section of 2-D seismic lines and two 3-D seismic blocks. Depths to the top of the Prairie Evaporite in this area range from 785 to 1050 m. The isopach of the formation varies due to proximity ...
Potash is mined worldwide to provide potassium, an essential nutrient for food crops. Evaporite-hosted potash deposits are the largest source of salts that contain potassium in water-soluble form, including potassium chloride, potassium-magnesium chloride, potassium sulfate, and potassium nitrate. Thick sections of evaporitic salt that form
Petrographically, the argillaceous halite of the ore zone is a compact megacrystalline evaporite rock. It consists of 90 percent or more of the mineral halite, and it invariably contains, besides clayey and silty detrital materials, one or more authigenic evapo rite minerals as a minor accessory constituent. Anhydrite, poly- halite, hematite, quartz, and magnesite are the principal and most
The most common naturally occurring potash minerals are carnallite and sylvite, with sylvite the most economically important, especially in the manufacture of muriate of potash fertilizer MOP. Other common potassium-entraining evaporite ore minerals include kainite, kieserite, langbeinite, leonite, and

Natural potash evaporites are a typical part of a brine evaporation series, crystallizing at the higher concentration or bittern end, either at the surface primary salts or in the shallow subsurface secondary salts. Today, bedded accumulations of primary potash evaporites are a relatively rare occurrence.

The main use of potash is as fertilizer. Sylvinite is the most important ore for the production of potash in North America. It is a mechanical mixture of sylvite KCl, or potassium chloride and halite NaCl, or sodium chloride. Most Canadian operations mine sylvinite with proportions of about 31 KCl and 66 NaCl with the balance being ...
Although potassium is a major constituent of many silicate minerals found in igneous, metamorphic, and sedimentary rocks, most of the worlds potash resources are found in subsurface, bedded evaporite deposits that produce high-grade, large tonnage orebodies, which afford low-cost mining and beneficiation Prudhomme and Krukowski, 2006.These are generally believed to have developed by ...

Aug 01, 2019 The Esterhazy Member of the western Canada Prairie Evaporite has been mined underground for sylvite KCl since the early 1960s. Although the geology of the Esterhazy Member ore body is largely considered a regional flat lying continuous series of thin potash hosting beds, there are numerous occurrences where the ore has been either replaced or removed leaving behind
Jul 25, 2016 Potash ore is extracted from two major ore deposit types, deeply buried marine evaporite deposits that typically range from 400 metres to greater than 1,000 metres below the surface, and surface brine deposits associated with saline water bodies such as the Dead Sea in the Middle East and the Great Salt Lake in North America.

An attempt is made here to synthesize the waste disposal problems of the potash industry in the Province of Saskatchewan, Canada. The problems are related to the type of ore mined and to the environment in which the waste disposal basins are situated.
