uma export mineral Dolomite is a transitory mineral. It has an intermediate composition between lime stone and Magnetite. It is mainly used as:
  • Ornamental stone
  • Raw material for the manufacture of cement
  • Source of magnesium oxide.
It is also an important petroleum reservoir rock, and serves as the host rock for large strata-bound Mississippi valley-type (MVT) ore deposits of base metals (that is, readily oxidized metals) such as lead, zinc and copper. Where calcite limestone is uncommon or too costly, dolomite is sometime used in its place as a flux (impurity remover) for the smelting of iron and steel. It also finds usage in horticulture, home and container gardening.

Calcite Mineral
uma export mineral Calcite is a carbonate of lime, that is abundantly distributed on the surface of the earth. It is mostly found in sedimentary rocks, lime stone in particular. It is also found in metamorphic marble. Calcite is often the primary constituent of the shells of marine organisms, e.g., plankton (such as coccoliths and plank tic foraminifera), the hard parts of red algae, some sponges etc. It is largely used in industries such as:
  • Textile
  • Rubber
  • Paints
  • Glass
  • Ceramic Paints

Soapstone/Talc Powder

uma export mineral Talc in its natural form is a hydrous magnesium silicate. It is used as a flux or cleansing agent for alumina ceramics, sanitary ware and dinnerware. It is comparably a low priced source of magnesium. It helps to produce less porous bodies at low firing temperature.
