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.
Figure 4: Typical schematic of solution mining processes in salt and potash  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.
Potash is currently produced from six potash mines in the Starobin area. Published reserves in the Pripyat Basin area are about 7.3 billion metric tons of potash ore (about 1.3 billion metric tons of K2O) mostly from potash-bearing salt horizons in the Starobin and Petrikov mine areas.
Jul 18, 2019· Advisian, the independent consulting arm of the WorleyParsons Group, provide end-to-end solutions, including Geosciences and Water Specialist Services globally. Advisian''s client, Kalium Lakes, is probably the most advanced of a small group of Australian exploration companies looking to produce high-grade premium Sulphate of Potash (SOP) fertilizer from potassium-rich brine.
Introduction. Currently there are eight mines in Saskatchewan where potash is mined using conventional underground mining techniques, and there are three solution mines. Within about a 100 km radius of Saskatoon there are five such mines, of which three: Cory, Allan and Lanigan, are owned and operated by .
Solution mining: A relatively new technique, introduced only a few decades ago, which involves dissolving the easily soluble potash salts in the deposits with fresh water via deep boreholes and bringing the solution to the surface in large containers. The warm solution is allowed to cool off, causing the potassium chloride to crystallize and ...
Some of this potash underlies Petrified Forest National Park (PFNP). Solution mining would be expected to recover about 30% of the resource while conventional underground mining could recover about 70%, in part because some minerals of the deposit are not readily soluble.
AECOM Regional Geology and Issues Report; HB In-Situ Solution Mine Project July 2010 5-7. The New Mexico Oil Conservation Division (OCD) is a cooperating agency in the implementation of the Order and potash lessees in the potash enclave can protest drilling permit applications to the OCD.
gree in Mining Geology from the TU Bergakademie Freiberg, East Germany and has a PhD in Natural Sciences from the Ruhr-Universität Bochum, Germany. Dr Rauche has practiced in the area of underground mining since 1976 in fluorite and barite mining, and since 1986 in potash and rock salt mining. He has been with ERCOSPLAN since 1997.
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.
Along the trend considered too deep for conventional mining a number of resource companies held permits, and several pilot solution mining projects were undertaken, such as the work of Imperial at Findlater Saskatchewan, Lumsden Potash at Bethune, and Lynbar Mining at Duval; however the only company to proceed with a commercial solution mining operation was Pittsburgh Plate Glass (PPG) at .
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 ...
Home / Solutions / 3D Geology & Mine Modeling We mine for solutions so you can mine for the rest. Proud of our cutting-edge technology and modeling methodologies, RESPEC develops 3D earth models to support many of its clients in potash exploration, salt dome storage, and resources characterization.
Regional Geology; Geology and Minerals Issues Related to the Proposed HB In-Situ Solution Mine Project _____ Prepared By: Bill Berg ... of oil production through the layers proposed for potash solution mining have created conditions that have not yet manifested themselves on the surface that could create hazards, not only due to subsidence, but ...
In all the other listed Quaternary examples there is no natural precipitate of potash, it is anthropogenically produced in salt factory facilities operating as brine concentrators, with inflow brine feeds derived either from modern lake brines or recovered by the solution mining of ancient evaporites.
The enabler of this concept is "selective solution mining." This technique borrows horizontal drilling from the oil sector and applies it to potash, rather than the typical vertical wells. Steve Halabura''s slide of the evolution of potash solution mining
Oct 27, 2015· In solution mining, saltwater (brine) is injected into the potash-bearing rock, which dissolves the potash, leaving everything else intact.

In conventional solution mining of potash intervals, all of the halite in the dissolution cavern must be leached along with the potash in order to keep the face of the solution cavity open and dissolving rapidly. Otherwise, a buildup of salt and insolubles on the active dissolution face cause blinding.
Patience Lake potash mine is located near the city of Saskatoon in the Canadian province of Saskatchewan. At Patience Lake potash is mined in situ by using a solution mining method where hot water is pumped through drillholes into the underground potash deposit and the resulting brine is then recovered through another set of drillholes and directed to the evaporation pond.
Ten active potash mines operate in the area (two solution mining mines, eight conventional underground mine). The closest mine is Lanigan Mine. The location of six potash mines within 50 km of the southern limit of the majority CPC''s permits also suggests that the local people will have experience in potash mine construction and operation.
