Dolomite mineral - You can buy these samples

Dolomite is a mineral, as well as a sedimentary rock, consisting of 95% of the mineral dolomite. May be confused with calcite, especially as it occurs in association with it. Just like calcite, it reacts with hydrochloric acid, but unlike it, it does not boil up, but slowly dissolves in it. Boils violently only in hot hydrochloric acid. Dolomite, depending on the chemical composition and color, has a number of varieties. Widely used in construction.

You can see dolomite stone for sale and buy it in the Minerals of Russia online store.
