Results of wet beneficiation process For the wet beneficiation process, three parameters; reaction time, temperature and reagent dosage were varied to determine the most effective method to use while trying to rid indigenous and foreign sodium bentonite and kaolin clay samples of their iron oxide impurities. 3.3.1.
Ground kaolin were dispersed in water and surfactants (1% of dried kaolin) were added. The powdered sample was soaked in deionized water for 24 h (one day). The layers were separated by decantation. The fine clay slurry has been dried at 60 °C and sieved about less than 75 µm so as to the fine grits for further analysis and characterization.
Kaolin is a clay mineral containing silica (SiO 2 ) and alumina (Al 2 O 3 ) in a high percentage which is an unreactive mineral in its natural form (Bendary et al., 2017;Rahayu et al., 2018).
The present communication reports the characteristics of the clay from the deposit and highlights the possibility of beneficiating it for various applications by adopting the known …
The present work aims to study a physical beneficiation of the Egyptian Kaolin from Kalabsha by using a wet high intensity magnetic filter. Since kaolin clay is an important for different industrial applications, but the presence of coloring materials such as iron and titanium, make it unusable for industrial applications as it affects the brightness and whiteness property.

Keywords: flotation, kaolin clay, hydroxamate collector, anatase, selective flocculation Introduction Kaolin clay is used extensively for paper coating and filler application, but it has to be processed to meet the industry specifications. It is also used as filler and pigment for various other materials, such as paint, rubber, plastic and resins.
Clay minerals are one of the most utilized minerals among non-metals. These are hydrous aluminum silicates with a layer (sheet-like) structure. Kaolin is a hydrous aluminosilicate mineral with a thin platelet structure. Kaolin is extensively used in paper, paint, and many other industries. Wet processing of kaolin will not be sustainable over the long term because global freshwater …
The average crystallite size of the raw kaolin and Beneficiated Kaolin Clay (BKC) was calculated to be 40.258nm and 28.114nm respectively. The XRD analysis showed that the BKC had four (4) different phases of kaolinite: Al(Si2O5)(OH)4, kaolinite 1Md – AlSi2O5(OH)4, quartz – SiO2 and muscovite – KAl2 (Si3Al)O10(OH)2.
Selective flocculation enables the production of high-brightness kaolin products from kaolin ore once considered too poor in quality for beneficiation into paper-coating pigments. Anatase, Ti(1−X)FeXO2, with X = 0 to 0.05, is a common iron-bearing impurity in sedimentary kaolin that can be unresponsive to kaolin beneficiation processes, such as …
