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
A simple method of removing iron from kaolin. published date: 2019/11/12. Kaolin, also known as clay, is named after the best quality of Jiangxi Gaoling. It is the main source of raw materials for the manufacture of ceramics. It contains not less quantitative ferroferric oxide, ferric oxide and iron.
Iron Removal From Kaolins By Bacterial Leaching. A process for biological removal of iron from quartz sands, kaolins and clays was developed as leaching at 90 oC with lixiviant produced as a result of beneficiation of kaolin quality in this study. KS1 sample of kaolin raw material (table 1) composed of wt. iron, which was found.

The iron removal process of kaolin magnetic separator is a magnetite drywet beneficiation magnetic separation process method. In the process of removing iron, the ore recycling rate can be improved, and the water consumption in the process of iron removal is small, saving Water, reduce production costs, reduce pollution, magnetic selection dust has a special dust removal device, will not
Deposits of hard kaolin are abundant in China, with kaolin content in the ore exceeding 95%. It is, however, rather difficult to remove iron from the ore. It was demonstrated that wet highgradient magnetic separation is very efficient in removing the iron compounds from kaolin. For hard kaolin, however, dry highgradient magnetic separation (HGMS) may be more suitable.
