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 crushed and broken stone.
DThe 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 occurence is presented on the map.
The table 1 below shows resources and the state of development and exploration of the dolomite deposits.
Production of dolomite was equal 3,102 thousand tonnes in 2010, increasing for about 163 thousand tonnes in relation to that in previous year.
The figure given below shows changes in domestic resources and production of dolomite in Poland in the years 1989-2010.
In 2010, Poland imported a total of 135.69 thousand tonnes of dolomite at the cost of PLN 21.22 million and exported 36.71 thousand tonnes for PLN 14.63 million. Directions of Polish import and export of dolomite are presented in table 2.
- B - for solid minerals - mine in building process, for fuels - prepared for exploitation or trial period of the exploitation
- E - exploited
- G - underground natural gas storage facilities
- M - deposit crossed out of the annual report of mineral resources during analized period
- P - deposit covered by preliminary exploration (in C2+D category, for fuels – in C category)
- R - deposit covered by detailed exploration (in A+B+C1 category, for fuels – in A+B category)
- Z - abandoned deposit
- T - deposit exploited temporarily
- K - change of the raw material in deposit
