A process for producing a high brightness, high solids kaolin clay aqueous slurry. An aqueous low solids suspension of crude kaolin clay is degritted, and subjected to a particle size classification. The aqueous suspension of the fine particle fraction is acidified to a pH of 5.0 or lower to produce an acid flocculated suspension which is treated with a bleaching …

Kaolin, or china clay, is defined as a white, claylike material composed mainly of kaolinite, which is a hydrated aluminum silicate (Al2O3·2SiO2·2H2O), and other kaolin-group minerals. Kaolin has a wide variety of industrial ... transported to the processing plant and stockpiled. In some cases, the crude clay is weathered for 6 to 12 months ...
Non-reinforced bioplastics (BP) and those containing 5 wt.% crude kaolin (BPKB) or metakaolin (BPMKB) were manufactured using the casting/evaporation method. Results obtained showed a decrease in the solubility and in the water diffusion and permeability of clay-reinforced bioplastics with respect to the ones without reinforcement.
Engineering property of kaolin clay contaminated by diesel oil was studied through a series of laboratory experiments. Oil contents (mass fraction) of 4%, 8%, 12%, 16% and 20% were selected to represent different contamination degrees, and the soil specimens were manually prepared through mixing and static compaction method. Initial …
addition, crude kaolin is frequently stained yellow by iron hydroxide pigments. It is often necessary to bleach the clay chemically to remove the iron pigment and to wash it with water to remove the other minerals, in order to prepare kaolin for commercial use (Byrne and Deasy, 2002; Sparks, 2003; Weil and Levchik, 2008).
In this study, a sample of crude kaolin clay originated from Milos Island, Greece, was used as raw material. The kaolin sample was ground to a particle size less than 250μm, before calcination. Chemical analysis of kaolin (Table 1) was ... crude kaolin taken from chemical analysis (Table 1). Based on the results of mass loss obtained from the ...
activated kaolin clay of 3M and 5M can be used with little or no difference in the bleaching efficiency. The result also shows that the optimal contact time for the bleaching process is 30 minutes at 120 for a dosage of 3g.

Leaching of kaolin clay was carried out for 3 h at 160 °C in an autoclave. Hydrochloric acid (20 vol %) was used as a leaching agent. The pulp after leaching was used for the thickening and filtering of Si-stoff. Si-stoff with a residual moisture content of 40–50 wt % was washed with water, which aimed to absorb HCl from the calcination gases.
Several types of clay are obtainable and applied in adsorption to treat the petroleum fractions [2, 6, 9-14]. Attapulgite clay can be used to separate crude oils into saturates, aromatics and resins through a chromatography column packed [6]. Bentonite is considered very good adsorbent clay and specifically commonly used as a sorbent
except kaolin (wet), feldspar (wet), talc minerals (flotation), garnet, and graphite. Mine drainage and contaminated plant runoff are considered separately for each subcategory. This study included 21 clay, ceramic, and refractory minerals of Standard Industrial classification (SIC) categories . 1452, 1453, 1454, 1459, 1496,
Then, the crude kaolin was suspended in deionized water (1:5 kaolin to water ratio) in the presence of a chemical dispersant (1% of sodium hexametaphosphate, Na 6 (PO 3) 6) and then stirred manually for 10 min using a glass rod and allowed to stand for 48 h. The dispersed clay was settled by gravity and fractionated into three layers: the …
