Several different types of kilns are used for the calcination process. These kilns can be rotary kilns or shaft kilns. The type of the kiln to be selected strongly depend on the characteristics of the raw dolomite, anticipated production rate, cost of fuel, investment costs, available fuel, local conditions, infrastructure and other things.

The thermal treatment of limestone (mainly CaCO 3) to produce lime (CaO) is a major contributor to CO 2 emissions and the literature on decarbonising the lime industry is scarce. Subsequent hydration of lime would lead to the synthesis of slaked/hydrated lime Ca(OH) 2; the production of a tonne of Ca(OH) 2 emits ∼1.2 tonnes of CO 2 arising …

The lime burning was carried out as a single firing or as a batch process when large numbers of locals would be involved. Because the lime kiln was filled from the top and could be unloaded from the top, access to the top of the kiln was necessary. The kiln was generally constructed on either a rock face, or earthen bank, to permit this.
