Kaolin Processing To Obtain Alumina

  • AMMG signs option agreement to acquire an exclusive .

    This unique technology process has successfully produced samples of 86 g of 99.99% high purity alumina and 1.06 kg of 99% smelter grade alumina from AMMG's Meckering kaolin. It is a unique kaolin to alumina technology via an acid-based process, whereby the separation of silica from the kaolin leaves 99-99.99% alumina.
