The dolomite is heated to a high temperature to drive off the carbonate as carbon dioxide and the remaining material, a mixture of calcium and magnesium oxides, is blended with carbon and other materials and pressed into blocks for the furnaces. The magnesium and calcium oxides have very high melting points and are an excellent, inexpensive refractory material.

Dolomite that was sulfated by this process was regenerated for subsequent reuse as a sorbent to CaO . MgO by reductive decomposition in a fluidized bed. Regeneration was accomplished by the incomplete combustion of methane in a fluidized bed of sulfated dolomite to generate the heat and the required reducing gases for the reactions at 1010 to 1100/sup 0/C. Experimental results indie that at ...
Lime production GB2009
The production occurs in vertical and rotary kilns fired by coal, oil or natural gas. Calcium limestone contains 97– 98 % calcium carbonate on a dry basis. The rest includes magnesium carbonate, aluminium oxide, iron oxide and silica. However, some limestone contains as much as 35–45 % magnesium carbonate and is classified as dolomite.
Dolomite – Ceramic Action
· Dolostone (dolomite rock) is composed predominantly of the mineral dolomite with a stoichiometric ratio of 50% or greater content of magnesium replacing calcium, often as a result of diagenesis. Dolomite is used as an ornamental stone, a concrete aggregate, a source of magnesium oxide and in the Pidgeon process for the production of magnesium.
Flow, dissolution, and precipitation in dolomite
dissolution of dolomite is a (slow) reaction rate limited process at room temperature [Lund et al., 1973]. The main aim of the current experimental research is to understand the evolution of hydraulic conductivity and flow patterns, caused by concurrent dissolution of dolomite and precipitation of calcium carbonate, in porous dolomite rocks.
