2003-11-1  The main characteristic, which determines the utility of the clay for various applications, is its purity. Pure kaolinite (Al 2 O 3 2SiO 2 2H 2 O) is white in colour and its chemical composition is 46.54% SiO 2, 39.50% Al 2 O 3 and 13.96% H 2 O (Grimshaw, 1971). Presence of impurities, particularly iron- and titanium-bearing materials, imparts colour to kaolin.

Beneficiation and Evaluation of Mutaka kaolin

2016-5-7  Kaolin is an important industrial mineral which often needs upgrading for special applications. The upgrading process, commonly known as beneficiation, is aimed at removing impurities like feldspar, quartz, iron oxide, etc. In this study, a kaolin sample was collected from a deposit located at Mutaka, South-Western Uganda, – the biggest kaolin deposit in the country. With the aim of upgrading this sample, it was processed by a laboratory hydro cyclone to produce a kaolinite concentrate and this has been characterized to ascertain its use as an industrial raw material. Characterization of the beneficiated sample was carried out by XRD, SEM, particle-size distribution, density and volume measurements, chemical analysis, whiteness index test, thermal analysis (DTA/TG) and surface area measurements. Results show that the laboratory beneficiation exercise improves the kaolin sample to a very high grade with a chemical composition close to that of ideal kaolinite. The major impurity after beneficiation,
