Beneficiation of a commercial kaolin from Mar de Espanha, Minas Gerais, Brazil: Chemistry and mineralogy Vijayendra Garg Raw materials used to produce a commercial kaolin from Minas Gerais, Brazil, and the intermediate and final products after processing were studied to trace the fate of iron during industrial beneficiation.
Kaolin is a commercial term used to describe white clay composed essentially of kaolinite. AL4Si4O10 (OH)8. The term is typically used to refer to both the raw clay and the refined commercial product. Although originally valued for use in the manufacture of whiteware ceramics, the principal use of kaolin is now in the filling and coating of paper.
Similarly, iron ores such as hematite may contain clays like kaolin as contamination which cause problems in the operation of blast furnaces. Therefore, the first beneficiation step to make these raw materials commercially valuable is to effectively eliminate iron oxides from kaolinite clays and vice versa (Poorni and Natarajan, 2013).

The vibration method of beneficiation compared with the hydrocyclone method, which at the present time is the most promising, has a number of advantages including: it ensures high output per used area, there is no need to use high pressure pumps and the beneficiation equipment is less subject to wear compared with hydrocyclones.
The kaolin ore dry beneficiation process is widely used in hard kaolin with high purity and good whiteness. The main process includes kaolin ore crushing-ore drying-separation. The kaolin ore excavated in the open pit is crushed by the rod-toothed crusher in advance and then sent to a drum dryer equipped with partitions.
The beneficiation of kaolin clay is improved by fractionating a kaolin clay starting material into a lower brightness first fraction having a majority of the discoloring impurities and a higher brightness second fraction with less impurities. The first fraction is then beneficiated (such as by flotation, selection flocculation, high intensity ...
