flocculation to remove iron from kaolin

Reduction of Titanoferrous Impurities from Kaolin by

Index Terms: kaolin, selective flocculation, polyacrylamide, iron, titania, zeta potential, selective adsorption, possibilities of bacterial leaching to remove high iron content present in kaolin. Different strains were used to leach iron from kaolin. The feed kaolin clay is highly contaminated with iron of 11% and 42% iron reduction is observed. Chandrasekhar S and Ramaswamy S [3, 14

Selective flocculation separation of iron and titanium

Selective flocculation separation of iron and titanium from Kutch kaolins (India) G V S S Kumara, S K Menona, Y resulted in 65.5% recovery of kaolin with the removal of 74.2% Fe203 and 76.0% Ti02 at pH ::::: 8 (Fig. 2). The brightness values of the products obtained with different f10cculant dosages are shown in Fig. 3. High brightness value of the product (82.0 units) was obtained with 4

Biological beneficiation of kaolin: A review on iron removal

01/04/2015· Iron oxide existence in kaolin is biologically induced, so it is better to apply a biological process for removing it from clays by exploiting microorganisms (Poorni and Natarajan, 2013). Interaction of microbes with clay minerals conserves the clay structure, fertility, and chemistry of the soil through the cation exchange and pH buffering ( Kostka et al., 1999a ).

PURIFICATION OF KAOLIN BY SELECTIVE FLOCCULATION

flocculation for removing its colored impurities such as rutile and anatase. This study was conducted in bench scale and it consisted of: blunging, screening, conditioning and decantation. Overflow and underflow resulting from settling of the flocculated material were then dried and submitted to TiO2 and brightness analyses. Sodium polyacrylate and sodium silicate were added to kaolin clay

Application of differential bio-flocculation in the

Abstract. Differential flocculation acts based upon the difference in the settling rates of two minerals. So, the application of the bacterial cells, spent medium, extracellular protein, and polysaccharide derived from a cell-free extract of Bacillus licheniformis were investigated to remove hematite and goethite from kaolin and quartz. The zeta potentials and settling behaviors of the

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-differential thermal analysis (TG-DTA) and X-ray diffraction (XRD) demonstrated that 900°C was the suitable temperature for the calcination. Leaching tests showed that hydrochloric acid was more effective for iron dissolution from raw coal
