Lime Production from Limestone Current Technology

3) Lime Calcining (Conversion of limestone (CaCo3) to lime (CaO)) Limestone is a source of calcium carbonate and is heated to convert the calcium carbonate into calcium oxide. This process is generally carried out in large rotary kilns or vertical shaft kilns where high temperature is required. Quicklime is produced in the calcination process
