Secondly, how do you process limestone? Limestone is extracted from the rock either by blasting or mechanical excavation depending on the hardness of the rock. rough crushing. After crushing the stone is sorted into different fractions by screening, after which it goes to be processed further.

Lime Processes. The dissociation of limestone (calcium carbonate) into quicklime and carbon dioxide at temperature is a process known as calcination i.e., CaCO 3 = CaO + CO 2 ΔH = -760 BTU/lb CaCO 3. Magnesium Carbonate, which is found in some quantities with limestone deposits, also dissociates according to the reaction: MgCO 3 = MgO + CO 2

Dolomitization. Dolomitization, process by which limestone is altered into dolomite; when limestone comes into contact with magnesium-rich water, the mineral dolomite, calcium and magnesium carbonate, CaMg(CO 3) 2, replaces the calcite (calcium carbonate, CaCO 3) in the rock, volume for volume Dolomitization involves recrystallization on a large scale.

Calcium carbonate is abundantly available in nature as limestone, chalkboard, or marble and CaCO 3 fillers from these minerals can be produced at very low cost. Three forms of CaCO 3 fillers are used arranged in the order of purity, they are dry processed, beneficiated, and precipitated. Calcium carbonate is considered a soft, nonabrasive filler.

Limestone is a sedimentary rock that is composed of the mineral calcite. When a drop of dilute hydrochloric acid is placed on this rock, it bubbles and fizzes as carbon dioxide is released. This reaction can only occur when a rock is composed of the mineral calcite (CaCO 3). Can you turn limestone into slate? This process is called metamorphism
