Solution Mining Karnalyte Resources

May 15, 2019Solution Mining. Conventional underground mining methods are predominantly used for Sylvinite potash mines throughout the world. The mineral Carnallite is deliquescent, with the ore absorbing moisture from the atmosphere. This tends to weaken the structural strength of the ore body, and renders it unsuitable for conventional mining.
