Dolomites

Dolomite is widely used in glass and ceramic industry, as a flux for smelting iron and steel, and in production of fireproof raw materials and cement. Moreover, it is also used in agriculture as raw material for production of calcium-magnesium mineral fertilizers.

Dolomite is also used in construction industry and road construction as building and crushed stone. These uses are discussed in the section on dimension and crushed stones.

The majority of pure dolomite deposits occur in areas of the Silesian and Lower Silesian regions and Małopolska Voivodeship. Raw materials from these deposits are characterized by the best quality and match economic criteria of a flux for smelting iron and steel. The deposits are of the stratified type and Devonian or Triassic in age, as for examples those from Żelatowa, Brudzowice and Ząbkowice Będzińskie.

Deposits of dolomites usable as a raw material for ceramic industry occur in the Lower Silesian region. The dolomites form lenses in metamorphic schists. The best known of these dolomite deposits are situated at Rędziny in the vicinities of Jelenia Góra and in the area of the Kłodzko Basin.

Dolomite deposits occurrence is presented on the map.

The table 1 below shows resources and the state of development and exploration of the dolomite deposits.

Anticipated economic resources amounted to 403.48 million tonnes in 2014 and increased by 68.89 million tonnes in comparison with the previous year. The growth was due to the new calculations of resources approved for Brudzowice (52.61 million tonnes) and Rędziny (18.11 million tonnes) deposits.

Anticipated economic resources from exploited deposits account for 56.83 % of total anticipated economic resources (amounted to 236.15 million tonnes).

Economic resources of dolomites increased by 56.83 million tonnes and are equal 128.29 million tonnes. These resources account only for 31.8 % of total anticipated economic resources.

Production of dolomite was equal 3,131.00 thousand tonnes in 2014, increasing by 296.9 thousand tonnes in relation to the previous year. The significant growth was noted for Brudzowice (by 301.8 thousand tonnes) and Rędziny (by 38.8 thousand tonnes) deposits. The exploitation from Chruszczobród 2 deposit was started in 2014.

The figure given below shows changes in domestic resources and production of dolomite in Poland in the years 1989-2014.
