11.25 Clay Processing

The cement industry has become one of the largest GHG polluters in the world . Most of the 2.9 billion t CO2 emissions are generated in clinker manufacturing from the calcination/decarbonation of limestone (carbon carbonate), the key raw material. Today, in the cement production, these process emissions account for a…See more on zkg.de

    Process for producing a kaolin clay product

    A process for producing a high solids aqueous slurry of a beneficiated kaolin. An impure crude kaolin clay is initially subjected to wet processing including a size classification step, to recover a beneficiated fine particle size kaolin fraction which is formed into a dilute aqueous slurry of deflocculated kaolin particles. The dilute slurry is filtered by flowing it generally parallel to and ...
