Abstract High-quality kaolins are produced from two sites in the Capim River area in Pará State, northern Brazil. One mine is operated by Rio Capim Caulim (RCC) owned by Imerys and the other by Pará Pigmentos S.A. (PPSA) owned by Caemi (CVRD Group). The kaolin deposits are located on low-relief plateaux with a lateritic cap. The kaolin strata are in …
