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 the potassium chloride.
Solution mining is used when the ore body is too deep for economical mining by conventional methods. The world's first solution mine is near Regina (Saskatchewan, Canada) where the ore was approximately 1500 m deep. The process consists of drilling into the ore body by injecting water and recycled spent water steams to dissolve the salts.
What is Solution Mining? SMRI views solution mining as mining of underground, water-soluble minerals, usually using one or more drilled wells to dissolve the minerals with water (not by using acids used in metal ore leaching). Minerals such as salt, potash, trona, and magnesium salts may be produced by pumping saturated fluid from underground ...
Process Development. We have a large amount of experience in creating new and cost effective potash processes for various clients. Our experience is in conventional and crystallizer MOP (KCl) and SOP (K2SO4) plants. Conventionally minded ore is the base of our expertise; from there, we have developed extensive experience in evaporation ponds.
Apr 29, 2016· The Southey Project is a proposed Greenfield solution potash mine located approximately 60 km north of Regina, in the Rural Municipalities of Longlaketon and Cupar. The projected production ...
The purpose of the Milestone Phase I Project is to test and optimize the horizontal solution mining method in Saskatchewan, and to investigate how the method can be applied to full-scale potash production. This Phase I Project is truely innovative and could revolutionize the way potash is .
Dec 02, 2016· Solution mining is a more energy intensive process than conventional mining. Comparing 11 potash mines in Saskatchewan, solution mining's average energy consumption was about 1300kWh/tonne and conventional mining's was close to 400kWh/tonne. Gensource plan to mine this deposit using the solution mining process instead of the underground ...
From there, the ore consist of potash, salt and clay, and must be milled in order to separate the potash. Mosaic pioneered an alternate technology called solution mining at its Belle Plaine facility in Saskatchewan. This process uses heated salt water, which is injected into, and pumped from, the ground in order to remove potash.
Jun 01, 2017· The solution mine, which is located 70 km northwest of Regina, will create more than 400 permanent jobs and have a mine life of more than 50 years. "With our new location, we are taking a huge step forward in the internationalization of our potash business," said Norbert Steiner, chairman of the board at K+S Aktiengesellschaft, in a release ...
Mining engineers stop short of their targeted cavern footprint so the secondary mining process can be initiated. By injecting hot brine into the cavern, the roof and walls begin to slowly dissolve the potash. During all stages of the solution mining process an oil blanket is injected into the cavern to prevent uncontrolled vertical mining.
Solution mining involves dissolution of the potash with water. Wells are drilled into the potash-bearing area (sylvinite bed) and water, later brine, is pumped down the wells to dissolve the potassium chloride (KCl) (potash product) and sodium chloride (NaCl) (waste salt) that is in the sylvinite bed.
In-situ leaching (ISL), also called in-situ recovery (ISR) or solution mining, is a mining process used to recover minerals such as copper and uranium through boreholes drilled into a deposit, in situ.In situ leach works by artificially dissolving minerals occurring naturally in a solid state. For recovery of material occurring naturally in solution, see: Brine mining.

An Introduction to Potash Solution Mining. ... Just like conventional methods, there is a time and place for solution mining, and the process comes with downsides that need to be carefully considered.
Figure 4: Typical schematic of solution mining processes in salt and potash [11] Solution mining provides an opportunity to mine soft rock at depths in which conventional mining would not be feasible. Due to the decreased requirement for labour in solution mining, lower operating costs are obtained.
Saskatchewan producers mine potash in two ways: conventional and solution. Conventional mining usually occurs around 1,000 metres below the surface. Solution mining can access potash reserves at depths exceeding 1,600 metres below the earths' surface. The majority of Saskatchewan potash is mined by the conventional mining method, where large ...
There are a number of existing and planned potash projects in Saskatchewan and Atlantic Canada using a solution mining process. The solution mining process involves the construction of a well field composed of at least two drill holes – one to send hot water down to the potash-bearing zones of rock, and another to bring the potash-laden brine up to the surface after percolating in an ...
We streamline mine logistics and underground storage systems, maximizing time on continuous potash miners and stockpile-and-storage bins to make the most of hoisting systems. Solution mining and brine ponds. Processing brine from potash solution mining and shallow brine-extraction wells is a core capability of ours.

Potash occurs in soft deposits generally associated with sodium chloride and varying amounts of clay slime, which because of its colloidal character, complicates the beneficiation process.. 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%.
Project Albany is a proposed solution potash mine in southern Saskatchewan located in CanPacific Potash's KL 262 potash lease. Project Albany is located approximately 50 km southeast of Regina near the Town of Francis and the Village of Sedley Saskatchewan in the rural municipalities (RM) of Francis No. 127 and Lajord No. 128.
The primary methods of potash ore processing are flotation (mechanical method) and hot leaching (chemical method). JSC Belaruskali uses both methods: Productions Units 1, 2 and 3 process the potash ore by flotation and Production Unit 4 uses the hot leaching method.
In this regard, Western Potash has engaged AMEC Americas Ltd in Saskatoon to perform a full feasibility study for the techno-economic assessment of a 2,800,000 tonnes of potash per annum solution mining and processing operations, to be located on their Milestone property, approximately 30 km southeast of Regina, Saskatchewan.
Belle Plaine and the Esterhazy potash zones from the solution mining process. It consists of setting a bridge plug in the casings of each well about a meter below the base of the Belle Plaine zone, cutting or perforating the casings at the base of the Belle Plaine zone and hydraulically fracturing along a clay seam between the two wells.
