We prepared red clays by introducing different percentages of PbO, Bi2O3, and CdO. In order to understand how the introduction of these oxides into red clay influences its attenuation ability, the mass attenuation coefficient of the clays was experimentally measured in a lab using an HPGe detector. The theoretical shielding capability of the material present was …

A layered composite of Fe 2 O 3-pillared bentonite (Fe-P-Bet), used as a catalyst in a Fenton-like process, was prepared and then its mechanical activation was studied in detail.The optimum conditions for preparation of Fe-P-Bet and the effects of mechanical activation on the catalytic activity of Fe-P-Bet were investigated systematically.

Ball Clay. Ball clays are hydrous aluminum silicates of approximate formula Al 2 O 3, 2SiO 2 2H2O. They are inert (insoluble, non-flammable, non-decomposing, non-polymerizing) and non-toxic by ingestion. See 'Silica' for more information. Ball clays contain free quartz, in some cases up to 25%. Do not breathe dust.

The bentonite is employed as a flux, making firing a less energy intensive process, and allows for the oxidation of magnetite to hematite ahead of the blast furnace (16). Pelletisation makes for a more efficient melting process due to a larger surface area to volume ratio, and takes place in a tunnel kiln, leading to ball shaped pellets.

Smectite. A highly plastic clay mineral related to montmorillonite (bentonite), more correctly, the name of the group on minerals that includes montmorillonite and other similar minerals. The following was obtained from Southern Clay Minerals: Smectite is a platy clay mineral. Three properties make smectite unique:

bentonite content was 1.0%. Pellets in this study were acid and oxidized pellets, the main form of solid phase consolidation in which was hematite recrystallization connection, and the main mineral composition of which was hematite. During the process of pellets roasted to consolidation, comprehen-

The ball-milling duration was set in the range from 0 to 1.5 h, as listed in Table 2. Next, the tableting process was conducted with 3 steps, namely weighing, mixing and briquetting. Firstly, approximately 10 g titanium-bearing iron sand after ball-milling was weighed. Next, the titanium-bearing iron sand was injected with atomized water.

pellets made from these fines were revealed through experiments involving dry ball milling and small-scale and pilot-scale test s. ... 1 # and 2 Indian hematite fines and bentonite. The ...

The bentonite–hematite (b–h) system was prepared by the mixing of hematite and bentonite at pH 6.0, and a hematite-coated bentonite surface was created. The physical and chemical properties of the above solids were studied from the information given by X-ray, IR and NMR spectra and by measurement of specific surface and point of zero charge.

Bentonite is the most widely used binder in iron ore pelletizing industry. The use of bentonite is favorable in terms of physical, mechanical and metallurgical ...

Bentonite is some mineral with high level uses in many fields and reasonable price, also is a good alternative instead of diatomite, used in: oil wells drilling, earth wells, making detergents, color hiding, making oil and its refinery, fabric softener, pet care, water refinery and clarification, oil absorbent, sewage drums, dam making, soil ...

The X-ray diffractogram shows that high barite iron ore Fig. 15. Effect of activated bentonite addition on the reduction extent of concentrate pellets containing 1.5% bentonite shows that the high barite iron ore concentrate fired pellets (reduction temperature 800 jC). a-hematite is the main compound present in these pellets.

Ball clays are kaolinitic clays that commonly consist of 20–80% kaolinite, 10–25% mica, 6–65% quartz, as well as organic matter. Ball clay is formed from the weathering and transportation by water of parent rocks. Seams in the same deposit will vary in composition, depending on the quantity of the principal and accessory minerals.

Mineralogical and technological characterization of ceramic raw materials from a new deposit located at Caxias city, Maranhão State—Brazil, was accomplished to determine their potential as raw materials for the ceramics industry in northeastern Brazil. The ceramic raw materials were collected from three different locations on the site and characterized by X-ray …
