used for manufacturing certain types of refractory bricks used in steel making.
The dolomite is heated to a high temperature to drive off the carbonate as
carbon dioxide and the remaining material, a mixture of calcium and magnesium
oxides, is blended with carbon and other materials and pressed into blocks for
the furnaces. The magnesium and calcium oxides have very high melting points
and are an excellent, inexpensive refractory material.
Dolomite is also used as a source of magnesium oxide for making magnesium metal
and for chemical uses, such as the common laxative milk-of-magnesia. Dolomitic
limestone's and dolomites are mined along with limestone and used for crushed
stone and aggregates for manufacture of pavement, concrete for construction and
as fill material. Dolomite is also used in some cement, as a source of magnesium.
Of course Dolomite is also used as mineral specimens.
Dolomite specimens from the perlis, Malaysia are very popular among mineral collectors and
dealers. The clear transparent specimens from Perlis,Malaysia are rare and unusual, and
are in high demand by Collectors.
Dolomite Rock is used as an ornamental and structural stone, and for extracting
certain metals from their ores. It is useful in the chemical industry in the
preparation of magnesium salts.
