Dolomite is widely used in the glass and ceramic industries, as a flux for smelting iron and steel, and in the production of fireproof raw materials and cement. Moreover, it is also used in agriculture as the raw material for the production of calcium-magnesium mineral fertilizers. Dolomite is also used in a construction industry and a road construction as the building and crushed stone. These uses are discussed in the section on Dimension and crushed stones.

The majority of pure dolomite deposits occur in southern Poland, in the areas of the Silesian and Lower Silesian regions (Dolnośląskie ans Śląskie Voivodeships) and Małopolskie 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 a stratified type and Devonian or Triassic in age, as for examples those from Żelatowa, Brudzowice and Ząbkowice Będzińskie.

The second type of dolomite deposits forms lenses within metamorphic schists. These dolomites are usable as a raw material for the ceramic industry, construction industry and road construction. They occur in the Lower Silesian region. The biggest of these deposits (Ołdrzychowice-Romanowo) is situated at Rędziny in the vicinities of Jelenia Góra and in the area of the Kłodzko Basin. It is placed in the chapter devoted to Dimension and crushed stones as the raw material is the basic component for the production of building grits.

The dolomite deposits occurrence is presented on the map.

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

Anticipated economic resources amounted to 527.12 million tonnes in 2017 and decreased by 1.89 million tonnes (0.36%) in comparison with the previous year. That was the result of the exploitation and losses.

Anticipated economic resources of exploited deposits amounted to 233.02 million tonnes in 2017 and accounted for 44.21% of total anticipated economic resources. The resources covered by the detailed exploration (categories A+B, C1) were equal 369.11 million tonnes (70.02% of total anticipated economic resources). Such resources within exploited deposits accounted for 98.37% of anticipated economic resources (229.23 million tonnes).

Economic resources of dolomites increased by 5.22 million tonnes and were equal 129.80 million tonnes. These resources accounted only for 24.62% of total anticipated economic resources. The resources growth was the result of a new deposit development plan approved for Chruszczobród 2 deposit.

Production of dolomite was equal 3,024.70 thousand tonnes in 2017, increasing by 286.68 thousand tonnes (10.47%) in relation to the previous year. The output grew significantly from Ząbkowice Będzińskie I deposit (by 171.46 thousand tonnes – 13.28%) and Brudzowice deposit (by 152.26 thousand tonnes – 14.94%). The slightly growth was noted for Żelatowa deposit – by 11.22 thousand tonnes (7.30%). For two other deposits there were drops recorded: - by 30.68 thousand tonnes (12.36%) for Rędziny and by 17.58 thousand tonnes (68.14%) for Chruszczobród 2.

The figure given below shows changes in domestic resources and production of dolomite in Poland in the years 1989-2017.
