Dolomite extraction is growing in the country2017-03-13
Based on the data of the Lithuanian Geological Survey under the Ministry of Environment, last year the total amount of dolomite extracted in the country totalled 1.3 million m3, i. e. 3 % more than in 2015.
It is found in various geological strata; however, only the deposits found near the surface of the earth in the northern part of Lithuania have practical significance. Dolomite is extracted in open workings, i. e. quarries, only. All the surveyed deposits and prospective sites are located in the districts of Pakruojis, Joniškis, Akmenė, Biržai and Rokiškis.
A total of eight companies have obtained permits to use dolomite resources, whereas five of them are engaged in dolomite extraction. The largest quantities of these resources are based in the district of Pakruojis. It is excavated in the Petrašiūnai II, Klovainiai and Krivaičiai deposits. There is also the Skaitsgirys deposit being exploited in the district of Joniškis. The preparation of the Čedasai deposit based in the district of Rokiškis for extraction is nearing completion. The Narbučiai (Akmenė district), Margiai and Petrašiūnai III (district of Pakruojis) have been earmarked for exploitation.
Dolomite is used in the production of breakstone, finishing boards, building stone and mineral wool and in the liming of acid soils. It can also be used in the production of lime, Roman cement and metallic magnesium as well as in metallurgy.
