Kaolinite Processing

23/8/2019The use of selective flocculation and high gradient magnetic separation to treat kaolin also obtained satisfactory indicators. Kaolin leaching Leaching is carried out in the presence of a weakly acidic solution (pH 3 to 4) in the presence of a reducing agent (NaS2O4) to keep the dissolved iron in the Fe2+ state, avoiding the formation of Fe(OH)3, and washing it

Chemical treatment of kaolin. Case study of kaolin from

Kaolin, obtained at the mine, mainly contains varying amounts of impurities such as iron oxide (Fe2O3) and anatase (TiO2). These components negatively affect the quality of the commercial product. This research was performed to improve the quality of kaolin to be used in the paper industry with the goal of reducing the impurities of iron and titanium oxides.

Flocculation of Both Kaolin and Hematite Suspensions

The flocculation performance of these two flocculants has been systematically studied using kaolin and hematite suspensions as synthetic wastewater under various pH conditions. CMS-CTA-P and CMS-CTA-N exhibited inverse flocculation behavior, but the commonness was that the starch-based flocculants with charge opposite to those of the contaminants in water always had higher flocculation

Iron removal by physical chemical way

However ground waters are naturally anaerobic: so iron remains in solution and therefore it is important to remove it for a water use. The elimination of the ferrous iron, by physical-chemical way, is obtained by raising the water redox potential by oxidation thanks to oxygen of the air and this by simple ventilation.

Influence of acid leaching and calcination on iron

Calcination and acid leaching of coal kaolin were studied to determine an effective and economical preparation method of calcined kaolin. Thermogravimetric Leaching tests showed that hydrochloric acid was more effective for iron dissolution from raw coal kaolin (RCK), whereas oxalic acid was more effective on iron dissolution from calcined coal kaolin (CCK).
