A through-diffusion method was used to investigate the Re(VII) (as a surrogate to 99Tc(VII)) diffusion in compacted illite-, hematite- and limonite-montmorillonite mixtures. The effective diffusion coefficient D e values were in the range of (4.29–6.71) × 10−11 m2/s at pH 3.0 and (3.44–5.72) × 10−11 m2/s at pH 9.0, respectively. Compared to montmorillonite, both D e and α values ...

Composition of drilling mud : Water-based drilling mud most commonly consists of Bentonite Powder (gel) with additives such as barium sulfate (barite), calcium carbonate (chalk) or hematite.Various thickeners are used to influence the viscosity of the fluid, e.g. xanthan gum, guar gum, glycol, carboxymethylcellulose, polyanionic cellulose (PAC), or starch.

The growth of granules in batch agglomeration of hematite iron ore powder with or without the presence of bentonite additive can be described by the non-random coalescence mechanism. The specific balling rate constant in the kinetic expression for median ball-size increases with increasing water content of the feed and decreases with addition ...

1 Introduction. Bentonite is a geological term for soil materials with a high content of a swelling mineral, which usually is montmorillonite. It is produced by in situ devitrifications of volcanic ash [].Although, bentonite chemical composition varies from one place to another place [].The bentonite clay is often extracted from open pit mines with different deposit depths and many impurities.

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.

binder, usually powdered bentonite, may be added to the concentrate to improve ball formation and the physical qualities of the "green" balls. The bentonite is mixed with the carefully moistened feed at 5 to 10 kilograms per megagram (kg/Mg) (10 to 20 pounds per ton [lb/ton]). The pellets are hardened by a procedure called induration.
