In the present work a preliminary study of iron removal from a yellow kaolin supplied by ECC International (Europe) Ltd. was performed using mainly oxalic and ascorbic acids in sulfuric acid solutions. The aim of the initial phase of research was to determine the effects of the main factors which can potentially influence the iron-removal process.
Kaolin is valued as a white pigment and therefore the goal in kaolin flotation circuits is to remove the colored impurities to result in an acceptable brightness product.

Generally, flotation processes remove Ti02 from the kaolin which improves product brightness. Iron content is not much affected by flotation. Unlike many flotation processes where the desired component is concentrated in the froth, kaolin flotation is the reverse of this, i. e., the undesired component is removed in the froth and discarded.
Sep 01, 1992· The floatation concentrate will contain the kaolin, and is removed from the floatation tanks in a kaolin-bearing stream 12, while the tails containing feldspar are rejected in stream 13. As will be noted from FIG. 2, this is the region of maximum difference in zeta potential between the kaolin and silica and the remainder of the silica and ...

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. Contaminants that are 1 …
copper flotation was investigated. It was found that bentonite and kaolinite affected the copper flotation in a different way. Increasing the proportion of bentonite increased the pulp viscosity that reduced the amount of froth on the top of slurry and decreased flotation rate, resulting in a lower copper recovery.
impurities, and separated into kaolin, feldspar and quartz sand. The feldspar and quartz exhibit a negative zeta potential across almost the whole pH range (4). However, the accompanying minerals that contain iron and titanium exhibit a positive surface charge to acid pH (5); thus, by floatation and the addition of anion-activecollectors for a ...

3. Results 3.1. Flotation. The total solids and water recovered from batch flotation tests for all conditions evaluated are presented in Fig. 1.The figure clearly illustrates the frothing properties of the hydroxamate collector, AM 28 (Basilio and Mathur, 2007), in that its addition resulted in increased froth stability as indicated by increased water recovery compared to equivalent tests ...
Kaolin is valued as a white pigment and therefore the goal in kaolin flotation circuits is to remove the colored impurities to result in an acceptable brightness product. Kaolin flotation originated with a novel carrier flotation process and later on carrierless flotation techniques were developed.

Abstract. In light of the problems of low-quality and low degree of comprehensive utilization of Guangdong muscovite-type kaolin, the reasons affecting the quality of kaolin were found to be a small amount of maroon powdery goethite adhering to the surface of kaolin and minor muscovite affecting the firing whiteness of products.
