Properties
Dolomite is calcium magnesium carbonate with rhombohedral shaped crystals. It is harder and more dense than calcite, and slightly more acid resistant.
Markets for Dolomite
As a mineral, Dolomite shares many of the same properties as limestone and can be used, for example, as an extender in paints, as a filler in carpet backing compounds and thermosetting resins and in the glass industry.
IMERYS is a leading producer of high brightness dolomite from production plants in Southwest France. The DRB range offers materials of a complete range of particle sizes, from fine particle size Calcidol which is ideal for Powder Coatings, to DRB 8/25 which is ideal as a filler in thermosetting resins.
