DOLOMITE INFORMATION

Most minerals have a range of atomic structures with variable amounts of impurities and substitutions. Not so with Dolomite which has an unusual constant ratio between its content of MgCo3 and of CaCo3.

USES FOR DOLOMITE

Dolomite is used mainly for acid neutralization in the chemical industry; however, it is also sometimes used as a soil conditioner, too.
