Potash ores generally contain 20 to 40 percent KCL with the balance being NaCl and a small amount of clay slime, the latter usually in the order of 1 to 1½%. Flotation has been developed as the principal separating process for the potash salts which generally are coarsely crystalline and free from the sodium salts at about 10 to 14 mesh.
Ore mining technology At present time the seams which are being mined are the seams of the 2nd and 3rd potash levels (seams II and III). The potash seam of the 1st level at PU 1 is being mined since 2004. The potash seam of the 4th level is considered as reserves projected be mined in the future. Mining methods: 1. Chamber mining
Potash mining, investment and price news from MINING. The latest news on potash mines and properties, mining companies and potash prices.
The Sylvinite ores mined in conventional mines contain Sylvite (20 to 30% K2O), Halite, sometimes Carnallite and 1 to 5% insol. Liberation, in some cases, is substantial at 1 cm (3/8 inch), and virtually complete in all cases at 14 mesh. The separation processes include dissolution of the Carnallite, and removal of the insols, followed by mechanical separation of Sylvite from the Halite.

The majority of fertilizer grade potash is processed using flotation processing. A second method, crystallization, is used mainly to produce Industrial and specialty-grade (white) potash. In both methods, impurities are removed from the potash ore, and the size of granules can be changed, but the final product is the same naturally-occurring mineral as was originally mined.
All commercial potash deposits come originally from evaporite deposits and are often buried deep below the earth's surface. Potash ores are typically rich in potassium chloride (KCl), sodium chloride (NaCl) and other salts and clays, and are typically obtained by conventional shaft mining with the extracted ore ground into a powder.

The majority of Saskatchewan potash is mined by the conventional mining method, where large mining machines are used to extract the ore by cutting tunnels into the ore body. The raw ore is then conveyed to a production hoist where it is transferred to the surface for processing.
Potash ore is extracted from deposits often deep below the earth's surface via either conventional underground mining or solution mining. Fluor's Mining & Metals team has extensive experience in developing feasibility study requirements, bringing certainty to function, cost and schedule for .
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).
Solution mining is different from the conventional underground mining method, which has been widely used in North America. Solution mining of potash ore involves injecting heated solvent into the underground potash ore via drill holes to dissolve potash. The dissolved salts are then pumped out of the cavern to a processing plant where the brine is evaporated and crystallized, leaving behind ...
Abstract. The mining of large underground potash deposits presents an unusual challenge because the quantity of ore to be mined is very large, the value of the ore is relatively low, there is extreme competition, and most dominately, at the depth of many potash mines there are severe stress and creep (plastic flow) problems.
