| Environmental use of limestone products Limestone products
Limestone is used to manufacture many different crushed and ground products sold with brand name Nordkalk.
Limestone products are used for soil improvement in order to neutralise acidity, for cleaning flue gases in power plants, for alkalising water, in animal feeds and as fillers in asphalt, paper and plastics, for example.
Nordkalk produces limestone products at ten sites in Finland, five in Sweden, three in Estonia and four in Poland. Dolomite is extracted at Kurevere in Estonia.
Production
The limestone usually has to be extracted by means of blasting but the softest types can be excavated by machine. The extracted stone is transported for rough crushing after which it is processed further, for example, by, crushing, sifting, grinding, refining or burning.
In Lappeenranta, Finland, Nordkalk uses a flotation process. The limestone is first ground into a wet slurry and the concentrated calcite is separated from the slurry by flotation
