O calcário é uma rocha sedimentar que é composta principalmente de carbonato de cálcio. Dolomite rochas são originalmente depositado como calcite ou calcário rico aragonite, mas durante o processo de diagenesis, a calcite ou aragonite é transformada em dolomita.

H.G. Machel, in Encyclopedia of Geology, 2005. Introduction. Dolomite was first described in 1791 as a rock by Deodat de Dolomieu, who investigated samples from the Italian Alps. Dolomites are of special interest because they often form hydrocarbon reservoir rocks. Despite intensive research for more than 200 years, the origin of dolomites is subject to considerable controversy.

DE Pool Filters. D.E. filters are the most efficient type of pool filter available to pool owners. It can trap particles down to 3 - 5 microns; well below what the naked eye can see, which is around 35 microns. DE filters, like most pool filters, use a pressure gauge to indicate the need for backwashing; when it reads 8 - 10 lbs. higher than the clean, or start-up pressure.

Calcined dolomite is a material that plays an important role in the steel sector, both for its purifying action and for the protection of refractory linings. Calcium and magnesium oxide or calcined dolomite are obtained from dolomitic minerals such as calcium carbonate and magnesium (Ca Mg (CO3) 2, through the calcination process.
