The beds of rock salt are mined or quarried by the usual excavation methods, depending on the depths and thicknesses of the deposits and on local conditions. The mined rock salt sometimes is dissolved and the salt manufactured by treatment of the brine, as described below. The method affords opportunities for purification of the salt.

Once the mine wall is undercut a special drilling machine bores small holes into the face of the salt. Then miners will prime these holes with explosive materials and prepare to start blasting. Blasting Miners ignite the explosives, creating a blast that dislodges 800 to 900 tons of rock salt in less than three seconds.

The drill-and-blast mining method begins by cutting into the rock salt face using specialized equipment. We then drill holes into the face and use explosives to break the salt into large rocks. Front-end loaders and trucks load and haul the salt to a crusher where it is reduced in size, loaded onto a conveyor belt and transported to a mill.
