Properties Chemical formula: CaMg [CO3] 2 - calcium and magnesium carbonate crystallographic system - trigonal Mohs hardness - 3.5 - 4 density - 2.8 -2.9 color - white, gray, yellowish, colorless Scratch - white fracture - shell cleavage - 3-way, perfect, in line with the walls of the rhombohedron gloss - glassy, sometimes pearl Forms isometric crystals (saddle-shaped rhombuses upward), sometimes plate or bar crystals. It occurs in clusters of granular, dense, crusts, veins and crystalline brushes. Creates pseudomorphoses after other minerals. It is brittle, transparent and shows luminescence: orange, green, yellow, brown, white, cream. Use in its pure form is used as magnesium ore (13.3% Mg - for light alloys) building material (for the production of special cement) decorative material raw material for the ceramics industry is used in metallurgy for the production of refractory materials for the production of mineral fertilizers (calcium fertilizer -magnesium for soil deacidification) Interests of collectors Properties it reacts with hydrochloric acid only after pulverization it is white, gray, yellowish, brown-gray, almost black texture - compact, massive, porous A distinction is made between secondary and primary dolomite : Primary dolomite is formed as a result of direct precipitation from sea water. It is fine-grained and even-grained. Secondary dolomite is formed as a result of metasomatosis, i.e. displacement of one component by another. In this case, calcium is displaced by magnesium. Secondary dolomite is coarse and unevenly grained print «Back | STRONA GŁÓWNA | KRUSZYWA DROGOWE I BUDOWLANE | NAWOZY | DOJAZD | KONTAKT | Copyright © 2016 Kopalnia Dolomitu Sp. z o.o.
