  • Biological Beneficiation Of Kaolin A Review On Iron

    Apr 01, 2015 High quality kaolins are also low in iron-bearing minerals. The existence of iron oxides in kaolin adversely affects the clay color, and reduces its brightness and refractoriness Ryu et al., 1995, de Mesquita et al., 1996, Lee et al., 2002, Mockoviakov et al., 2008. These cause a dramatic decrease in its commercial price Guo et al., 2010. Even an amount of 0.4 of oxides, hydroxides and hydrated oxides of ferric iron may be enough to impart a red to yellow pigmentation to clay

  • Kaolin Imerys

    Metakaolin is manufactured by the calcination of kaolin to form an amorphous pozzolanic white mineral additive for use in cement based products. Calcined Kaolin is an anhydrous aluminum silicate produced by heating ultrafine natural kaolin to high temperatures in a kiln. The calcination process increases whiteness and hardness, improves electrical properties, and alters the size and shape of the kaolin particles.
