2.2 Solution mining 2.2.1 Solution mining subsurface operations. This type of mining starts by the injection of fresh water through two injection wells directly into the underground ore body to dissolve the contained muriate of potash in situ.The impregnated brine is brought to the surface processing plant by the extraction well to remove the dissolved potassium chloride product.

SOLUTION MINING In 1992 there were only two commercial potash solution mining plants that had been specifically designed for that operation, and each appeared to be using single wells for injection and brine recovery. The oldest was the Kalium mine producing potassium chloride near Belle Plaine and Moose Jaw, Saskatchewan, Canada.

Solution mines do not require large-scale infrastructures, such as kilometre-long shafts and tunnels, and are, therefore, more economically viable. However, Solution Mining uses millions of cubic meters of fresh water each year to mine and produce potash. HLD Mining uses a negligible amounts of fresh water and primarily only for processing.
