The potash deposit in Bethune, Canada, contains the mineral potassium (26% potassium chloride content). Here, we use solution mining, which is the process of mining underground water- soluble minerals by dissolving the minerals with water. The mineral-rich solution called brine is then extracted from the ground and the minerals are recovered from it. As the solution mining process is water and energy intensive, great efforts have been taken to conserve and re-use as much of the natural resources as possible.
