Method for the calcination of calcium carbonate bearing ... · The process of this invention may be utilized, for example, to calcine the vast quantities of the limestone/dolomite fines currently discarded during the feed preparation process for the shaft kiln, stone preheater kiln and straight kiln calcination systems that are the current method of choice for producing lime and dolime.
crushing and calcination of dolomiteCalcination of dolomite involves heating the raw material at sufficient temperature in order to release the carbon dioxide from its carbonate minerals. This process is commonly conducted in a rotary kiln. There have been a number of calcination studies in a laboratory scale, but the study of dolomite calcination in a larger scale is very scarce.
The Pidgeon Process | Sovran White International Limited2. Calcination of the dolomite: The dolomite is calcinated by roasting it at 1,1001,200ºC to remove the carbon from the magnesium carbonate compound in the form of carbon dioxide. The heat energy required is supplied by gas generated from our SemiCoke crackers. The calcined dolomite is then delivered to a store house for cooling. 3.
