Two analogues of aggregates (calcite and dolomite) found in nuclear power plant (NPP) concrete have been neutron irradiated to fluences up to 2 × 1020 n/cm2 at 52 °C and 4 × 1019 n/cm2 at 95 °C (E > 0.1 MeV). X-ray diffraction studies showed that these aging conditions affected crystallography of both calcite and dolomite, with both showing a growth in their unit cells compared to that of

Dolomite mining process. The mining process at dolomite mine is based on conventional drilling and blasting followed by loading and trasportation of ore and waste by shovel and truck. Two types of ore are selectively mined. "On-grade" ore is of such good grade that it needs no further treatment than crushing,washing and screening before being

Dolomite Processing Plant. Dolomite is one kind of carbonate mineral which includes iron dolomite and manganese dolomite. The dolomite can be used in building materials, porcelain, glass and refractory after crushing. In chemical industry, agriculture, environmental protection, energy conservation, etc, the dolomite is also in a great demand.

Dolomite, like calcite, cleaves into six-sided polyhedrons with diamond-shaped faces. Relations between lamellar twinning and cleavage planes of dolomite, however, differ from those of calcite (see figure), and this difference may be used to distinguish the two minerals in coarse-grained rocks such as marbles.

Dolomitization is a geological process by which the carbonate mineral dolomite is formed when magnesium ions replace calcium ions in another carbonate mineral, calcite.It is common for this mineral alteration into dolomite to take place due to evaporation of water in the sabkha area.

Calcite also exhibits several twinning types. Such variability results in several thousand known crystal forms of calcite. Other polymorphs of calcium carbonate are hexagonal aragonite and vaterite, which are metastable and recrystallize into calcite under Earth''s near-surface conditions. However, this process can take many million years to finish.

Calcite is composed of calcium carbonate (CaCO3) while dolomite is a calcium magnesium carbonate (Ca Mg(CO3)2). The most common use for Gladstone is in the construction industry. It is crushed and sized for use as a road base material, an aggregate in concrete and asphalt, railroad ballast, rip-rap or fill.

Calcite’s name comes from ‘chalix’ or ‘chalx’, which is the Greek word for lime (‘calx’ in Latin). For over 5,000 years, calcite has been used to manufacture lime (CaO, calcium oxide). Although the equipment used to do this has changed across the centuries, the basic process remains the same.

Dolomite was first described as mineral in 1792 by Swiss naturalist Nicolas de Saussure. As a peculiar type of limestone, however, it was already known. Miners named the dolostone “Bitterspat” and “Murakalzit,” due to its similarities to real limestone, which is composed mostly of the mineral calcite. Is dolomite natural?
