(Figs. 1, 2, 3). This will include salt, potash and anhydrite/gypsum, which are economically important, dissolution collapse relations, key marine carbonate member markers and simple and complex folds. Malagawatch is selected to represent the deep saline basin facies with most of the major cycles present and locally very complex structure.


This is due to heat loss of the brine occurring while being pumped to the mining zone and the endothermic nature of potash dissolution. During the cold winter months, heat transfer from the brine to the atmosphere and surface casing can also be considerable, as the solvent brine may be exposed to surface ambient temperatures ranging from −20 ...

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, …


Mr. Jornayvaz served, directly or indirectly, as a manager of our predecessor, Intrepid Mining LLC, from 2000 until its dissolution at the time of our initial public offering in 2008. Mr. Jornayvaz has over 15 years of experience in the potash mining industry and over 30 years of experience in the oil and gas industry.


potash bearing zones were discovered as a result of oil and gas exploratory drilling (Davis 2009). Potash mining and production began in the 1930s. As a precautionfo r the potash mines in this region, the mining companies historically left protection pillars around the oil and gas boreholes (Intrepid Potash/Shaw 2008).


This initiative is expected to achieve a CO2 emissions reduction of 30 – 40% for shipments handled by Oldendorff. The estimated savings can be of up to 45,000 tonnes of CO2 per year, equivalent ...


The dissolution of the Uralkali/Belaruskali cartel is bad news if you are a potash producer, but good news if you are a farmer. Estimates are that potash prices might decline to $300 or less a ton, down from the current $400, as the Russian producers increase their volume. That means farmers will pay less for this crucial nutrient.


Ambitious Mining Project to Meet the Demand for Potash. Potash is an industrial mineral widely used as a fertilizer. It is mostly derived from potassium chloride (KCl), which is also known as Muriate of Potash (MOP). As a source of soluble potassium, potash is vital to the agricultural industry as a primary plant nutrient.


dissolution of highly soluble rocks and may result in overburden collapse that propagates to the surface, thereby damaging surface and subsurface resources. Oil and gas exploration and production has taken place in the potash mining area since the 1920s. The potash


By dissolving only, the highest grade of potash beds, the process will create a high potash concentration solvent which will minimize processing costs. If the solvent brine is warmer than the formation temperature, the Operator will be able to selectively control dissolution of the potash and in this way leave waste salt behind in the mining seam.


Kore Potash provide DX Project update. Kore Potash plc, a potash development company with 97%-ownership of the Kola and Dougou Extension (DX) Potash Projects in the Sintoukola Basin, Republic of Congo (RoC), has announced an update on the DX Potash Solution Mining Project definitive feasibility study (DFS) and the recent drilling …


Gensource is not inventing selective dissolution, and the concept has been discussed as being an optimal approach since 1967. Selective dissolution of potash has been successfully deployed at Intrepid Potash's Cane Creek Mine (Moab, UT) since 2002. Therefore, Gensource is not reinventing the wheel; we are just perfecting it for Saskatchewan.

The United Kingdom recently approved an underground potash mine deep in the North York Moors National Park to York Potash Ltd., which is a wholly owned subsidiary of Sirius Minerals PLC. York Potash will be extracting polyhalite, a mineral with agriculturally significant amounts of potassium, magnesium, sulfur, and calcium. "Polyhalite was ...


KCl is by far the most widely used K fertilizer for direct application and for the manufacture of N-P-K compound and bulk blend fertilizers. World standard fertilizer grade KCl (sometimes known as muriate of potash, MOP) contains 60–63% K2O and varies in colour from pink to brown or white depending on the mining and recovery processes used.


Now that I'm back from a great trip to Dallas to give a presentation and visit with many friends, I will continue to post about the Carlsbad Potash District.


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 …

Potash is mined using two and four rotor continuous boring machines. They can mine up to 900 tonnes per hour, making paths of up to 7.9 metres wide and 3.7 metres high. 3. Ore Storage: Conveyor belts carry ore to underground bins where it is stored until it is transported to the loading pocket of the shaft hoist. 4.

However, in geological fault zones, dissolution of the salt body due to contact with migrating groundwater may ultimately lead to the formation of geogenic caverns and subsidence of overlying structures representing a high risk to active potash mining. Due to the high solubility of potash salts, cavern growth is facilitated in potash seams ...
