  • Lime Production from Limestone Current TechnologyChallenges in Limestone Processing

    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 which can be crushed depending on it s useCommon limestone processing methods that prepare the material for subsequent manufacturing stages include drying calcining pre conditioning and pelletization The following information highlights limestone processing issues associated with these techniques as well as general material challenges associated with limestone manufacturing
