Q:What is the cause of dolomite?
Dolomite crystals belong to the three system of carbonate minerals 1. The chemical composition is CaMgCO32. Magnesium substituted for dolomite, manganese, etc.. When the number of iron or manganese exceeds that of magnesium, it is called dolomite or manganese dolomite. Three crystal system, crystal is rhombohedral, crystal surface is often bent into saddle shape, poly double crystal is common. Aggregates are usually grainy. Pure is white; gray when iron; brown after weathering. Glassy luster. Slowly foaming when cold hydrochloric acid is diluted. It is the main mineral of dolomite. Marine sedimentary dolomite is often interbedded with siderite and limestone. In lacustrine sediments, dolomite and gypsum, anhydrite, halite, sylvite, symbiosis.
Q:Is iron and calcium and magnesium replaced?
A carbonate mineral of calcium and iron. Pure dolomite has not been found; in natural species, a lot of magnesium or manganese displaces iron. Dolomite is a member of the chemical replacement series of dolomite (dolomite), which completely replaces iron in the crystalline structure of dolomite. The physical and chemical properties of dolomite are the same as those of dolomite. The chemical formula is Ca (Fe, Mg) (CO3) 2.
Q:Use of dolomite powder
The chemical composition is CaMg[CO3]2, the crystal belongs to three square system carbonate mineral. The crystal structure of dolomite is similar to that of calcite, the crystal shape is rhombohedral, and the crystal surface is often bent into saddle shape. White marble is white, because it contains other elements and impurities sometimes greyish green, gray yellow, pink color, luster glass. The three groups were full cleavage and brittle. Mohs hardness of 3.5-4, the proportion of 2.8-2.9. Mineral powders react slowly in cold, dilute hydrochloric acid.
Q:Which is more expensive, calcite or dolomite?
Calcite color varies because of containing impurities, such as iron containing manganese is yellow, reddish brown, black and so on.
Q:Dolomite used for dolomite
The utility model is also used as a flux in the fetal glaze. Some North kiln field, such as Ding often add dolomite in glaze, dolomite glaze in Jingdezhen also joined some.
Q:Is dolomite useful in shale?
Shale was formed in lentic environment, sediment deposition after a long time, so often exist in the lake and river deltas, formed in the continental shelf is shale, shale often contains ancient fossil plants and animals. Sometimes there are animal footprints, even traces of ancient raindrops may be preserved in shale.
Q:What's the difference between calcite and dolomite??
The original calcium carbonate in the geological structure changes of sedimentary process, have eroded ancient seawater, contains large amounts of magnesium ions in seawater, calcium ion and magnesium ion in calcium carbonate was carried out in part exchange, this process is called dolomitization, more fractured dolomite than calcium carbonate rocks. So the permeability is better. The difference in finding underground minerals especially helpful oil.
Q:What is the technological process of calcining dolomite in rotary kiln?
Metallurgical dolomite refers to the use of rotary kiln and shaft kiln sintering is the dolomite clinker, crushing, powdered refractory material which is made of proper size after sieving. We said magnesium also need calcining in rotary kiln and using dolomite as raw material, if using dolomite clasts as raw material to sinter calcium oxide rotary kiln production free when the particle size of the product is smaller and uniform, sometimes without breaking can be directly used for metallurgical dolomite kiln. The sintered dolomite is divided into three grades according to the content of calcium oxide and Magnesium Oxide.
Q:What is dolomite?
For variety is carried by the female 'tannike' (Tineke), male (Zaria) hybrid 'Charlier' foster accessShrubs, erect branches, medium thickness, stiffness, stem epidermal spines, spines straight, slightly red, the number of medium; leaf blade leathery green, small to medium, serrated leaf clear, obvious, weak surface gloss, 5 lobular, apical leaflets elliptic, nearly 3 scape leaflets entire; flowers high Xinqiao angle goblet type; the flower diameter of 9 ~ 12cm, 95 ~ 100 the number of petals, white, fragrant; stamens RHS155C; flowers pale yellow; cut the branch length of 60 ~ 70cm, 14 ~ 16 branch flower yield / plant / year, vase period of 10 to 15 days.
Q:What stage of dolomite is used in steelmaking?
The purpose is to improve the Magnesium Oxide adding dolomite content in slag, and replaced a part of limestone.
We have mastered our profession and have deep understanding of the market as well as the various processes which are engaged in extraction of these minerals. All these minerals are extracted on the basis of geographical location, climatic conditions as well as soil. The vermiculite is mined and refined using a variety of techniques and supplied commercially in a range of particle size grades of vermiculite concentrate. We have a clear understanding of the industry and the market where our minerals find their usage.
