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.

Kaolin Flotation: Beyond the Classical

2016-10-22  Recovery offine particles has been considered to be a major limitation of the classicalflotation pro- cess. However, the beneficiation of kaolin, a naturally occurringfine ore, via flotation has been practiced over the last 40years. Kaolin is valued as a white pigment, and therefore, the goal in kaolinflotation circuits is to remove the colored impurities to result in an acceptable brightness product. Kaolinflotation originated with a novel carrierflotation process, and later on carrierless flotation techniques were developed. The collector chemistry utilized to beneficiate kaolin is based on fatty acids, and recently hydroxamates have been successfully used. The purpose of this paper is to cover theflotation practice in the kaolin
