Dolomite

Dolomite is the name of a carbonate rock consisting of the mineral dolomite. This type of rock is closely related to limestone. It is formed by limestone being exposed to a process called dolomitisation, which, in brief, involves some calcium ions being replaced by magnesium ions. The chemical formula becomes CaMg(CO3)2.

How it’s produced:

Like limestone, dolomite occurs both in sedimentary and crystalline form. Sweden has no known occurrences of sedimentary dolomite. All dolomite in Sweden is crystalline and very ancient (around a billion years old). Norway has younger crystalline dolomite in mountain bedrock, while Estonia and Latvia have sedimentary dolomites that are the same age as the limestone on Gotland. Occurs in: primary rock and mountain bedrock. The dolomite is quarried, crushed and ground to the appropriate fractions at our various production plants and can then be processed into burned dolomite.

 

Uses:

Common applications for dolomite are in agriculture, because of its high magnesium content, and as a filler primarily in the paint and plastics industries.
