Most salt mines operate underground but in salt deserts the rock salt is also mined at the surface. Two main methods of extracting rock salt are used in underground mining: Cut and blast mining consists in cutting slots at the base of the rock face. A series of carefully sited holes are drilled and then charged with explosives to blast the rock.

Rock Salt Production Methods - Salt Production Line

Salt Mining | HowStuffWorks

In solution mining, wells are erected over salt beds or domes (deposits of salt forced up out of the earth by tectonic pressure) and water is injected to dissolve the salt. Then the salt solution, or brine, is pumped out and taken to a plant for evaporation. At the plant, the brine is treated to remove minerals and pumped into vacuum pans, sealed containers in which the brine is boiled and ...
