free iron from Kerala kaolin is removed by CDB treatment whereas in Gujarat kaolin both free and structural iron associated with titanoferrous impurity was difficult to remove. The crude kaolin contained 1.63 and 0.66 % TiO2 in Kerala and Gujarat kaolin respectively. Reduction of TiO2 in case of Gujarat kaolin was from 1.63 to 0.99%.
The mineralogical, morphological, chemical characteristics of the coal-series kaolin were analyzed in order to liberate quartz from kaolin. Single mineral flotation tests of pure kaolin and quartz was carried out to evaluate flotation responses in the presence of an amine collector (DDA) and three depressants (HF, sodium silicate and starch).
A chemical process is described for removing ferric iron present in submarginal quantities in concentrates of kaolin, quartz, titanium minerals, ceramic minerals for glass, paper and electronics use and other materials of industrial interest by which ferric iron is reduced to ferrous iron using acid solutions, possibly in the presence of low concentrations of sugars containing 5 or more carbon ...

Based on research work by Fuerstenau (1980), Huang, Li and Hu (1984), Hui and Wei (1991), Shergold (1978), and Zambrana et al (1974), we have investigated a two-liquid flotation technique for iron removal from kaolin and obtained some success.
Aug 15, 2019· 4 High-gradient magnetic separation technology has greatly changed the appearance of the kaolin industry. Especially the vibration high-gradient magnetic separation can effectively remove the iron-titanium impurities in kaolin, but has little effect on the particle size composition and physical and chemical properties of the product.
Kaolin is an important industrial mineral having numerous uses and requiring various market specifications. High brightness kaolin clays represent a continuing challenge to the producer. An advancement in this field of Kaolinite Clay Beneficiation has been a patented process developed by Minerals and Chemicals Philipp Corporation and termed Ultra Flotation.
With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century's practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.
