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. Brine is returned to the surface and is ...
Mining capital projects Are you ready for the next CapEx . costreduction strategies have taken effect Now the cycle has turned, CapEx must increase mineral discoveries 4 Further, as the demand for project investment has become more common Also, large processing original equipment manufacturers (OEM) have expanded their offerings significantly, moving into the engineering
Oct 27, 2015 For all of the reasons mentioned above, capex for selective dissolution potash projects is a fraction of conventional mining and solution mining. …
Aug 01, 2019 Over a seven year mine life, the underground mine is forecast to produce an average of 117,000 oz. gold per year at cash costs of US$516 per oz. and AISC of US$717 per oz. Ore from the Triangle zone at Lamaque is being processed at the existing (refurbished) Sigma mill, which contributed to the mine’s low capex of under $200 million.
Lesson: Potash Solution Mining – Dissolving Potash Overview Students will discover through guided inquiry and hands on activities that one of Saskatchewan’s valuable mineral resources is a mechanical mixture which is mined by conventional underground methods or by dissolution in water.
In contrast to traditional solution mining, which uses fresh water to dissolve potash and salt underground, selective dis solution uses brine to dissolve only potash from underground caverns. The new method is a real ‘gamechanger’ for the industry, according to Ferguson.
Traditional underground tunnel mining of potash has significant CAPEX and infrastructural requirements. Drilling shafts and tunnels for underground mining is expensive and brings a lot of salt waste to the surface to be stored. Underground mines also require large production capacities to be able to amortize CAPEX.

Dec 21, 2016 The pilot plant was designed to have an annual production capacity of 146,000 tonnes of potash obtained through horizontal mining of the Prairie Evaporites. The solution mining plan is based on the concept of 'selective solution mining' where the solvent is near-saturated with sodium chloride and partially saturated with potassium chloride.
