Salt production: rock mined salt - EUsalt: European Salt ...

Rock salt refers to the dry salt extracted from saliferous rock layers with the help of mining methods. 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 ...
