Dolomite may refer to: . Dolomite (mineral), a carbonate mineral Dolomite (rock), also known as dolostone, a sedimentary carbonate rock Dolomite, Alabama, unincorporated community in Jefferson County; Dolomite, California, unincorporated community in Inyo County; Dolomites, section of the Alps; Triumph Dolomite (1934–40), sporting cars made by Triumph Motor Company
Dolomite, also known as "dolostone" and "dolomite rock," is a sedimentary rock composed primarily of the mineral dolomite, CaMg(CO 3) 2. Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater. Dolomite and limestone are very similar rocks.
Calcination, the heating of solids to a high temperature for the purpose of removing volatile substances, oxidizing a portion of mass, or rendering them friable. Calcination, therefore, is sometimes considered a process of purification. A typical example is the manufacture of lime from limestone.
(2015) added chloride additives during the calcination process of dolomite rocks, leading to a decrease in the decomposition temperature of magnesite while controlling the thermal decomposition for calcium carbonate (CaCO 3) as well, resulting in a weakening of the negative effects of free lime (f-CaO) on cement. All of these experiences have ...

The effect of time, temperature, and pressure of carbon dioxide upon three types of dolomite is brought out. Dolomites are either double salts or solid solutions or mixtures of the two. The effect of lime and silica is pointed out. Dissociation, tensile strength, volume change, time of set, and weather test data are given.

The process of calcination derives its name from the Latin calcinare (to burn lime) due to its most common application, the decomposition of calcium carbonate to calcium oxide and carbon dioxide, in order to create cement.The product of calcination is usually referred to in general as "calcine", regardless of the actual minerals undergoing thermal treatment.
Sep 30, 2012· For dolomite mining and crushing to required fineness, we usually use the jaw crusher as the first dolomite crusher equipment and the impact crusher or cone crusher is usually used as secondary or ...
May 01, 2013· Highlights Calcination of dolomite greatly increased the surface molar ratio of Mg/Ca. Borate was more effectively removed with the calcined dolomite at lower temperatures. Calcined products under Ar showed the greater sorption density of B than under air. Reactivity with H 3 BO 3 was affected by CO 2 gas generated in calcination of dolomite.
Dec 05, 2017· Calcined Dolomite or FluxDolomite is the name given to the quicklime formed from calcininga natural dolomitic limestone that contains nearly an equal molar weight percentage of calcium oxide to magnesium oxide.
(Glossary - Unspecified) Calcination. The calcining process is used to remove some or all unwanted volatiles from a material (e.g. H2O, CO2, SO2) and/or to convert a material into a more stable, durable or harder state. Varying temperatures are employed to calcine various materials, depending on the decomposition temperature of the vol...
The invention provides a process for producing magnesium hydroxide and calcium carbonate by the dolomite conversion method. The process comprises the following steps: calcining dolomite, carrying out a digestion reaction on dolomite and water and refining so as to obtain a refined slurry of calcium hydrate and magnesium hydroxide; reacting the slurry with an ammonium chloride solution to ...
The Kinetics of Calcination of High Calcium Limestone P. C. Okonkwo*, S. S Adefila ** Department of Chemical Engineering, Ahmadu Bello University, Zaria Nigeria; ABSTRACT The kinetics of calcination of a high calcium type of limestone was studied. Ukpilla limestone found in .
What is the difference between dolomite and calcined dolomite? I am going to conduct gasification experiment using calcined dolomite as bed material to improve the gasification performance.

Natural dolomite was calcined at different temperatures in the range 873-1373K and characterized by X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy, and N 2 adsorption/desorption isotherm. The calcination temperature had considerable effect on the surface chemical composition, crystallinity, and basicity of CO 2 gas sorption of each component in the .
Dolomite Calcination Plant is the calcination process of dolomite, which is the first step in the process of magnesium production.
Jan 22, 2009· 2.1 Process Emissions Major carbonates used in the production of glass are limestone, dolomite, and soda ash. The use of these carbonates in the glass manufacturing process is a complex high-temperature reaction that is not directly comparable to the calcination process used in lime manufacture and
A rotary calciner (rotary kiln) is used for a variety of thermal material processing applications. Elan now offers contract or toll processing services with the use of our rotary kiln — offering calcined clay, calcined petroleum coke, calcined gypsum, calcined kaolin, calcined bauxite, calcined alumina.
applications of dolomite depend on its physicochemical, structural, and thermodynamic properties. Knowledge of kinetics thermal decomposition of min-erals is very important for the calcination process in industrial production. The kinetics of the thermal decom-position of dolomite .
