1. Introduction. Bentonite is the conventional binder in iron ore pelletization and used at 0.5–1.5% addition levels in the pellet feed by weight of iron ore [1], [2], [3].It controls the moisture of iron ore concentrate in the pellet feed and improves physical properties of the wet, dry, pre-heated and fired pellets.

The mold consists of silica sand, coal, binder (bentonite) and moisture (Cruz et al., 2009). Binder is a compound that imparts strength to the mold by adhering to sand grains and bonding them together. The surface of bentonite binder is ionic, which in the presence of water, helps in the creation of a sticky coating on the surface of sand grains.
Conventional diffraction equipment can be used for crystalline silica analysis at the present detection limits required by safety standards. Relatively simple modifications of the diffractometer will increase its sensitivity to small amounts of silica and improve the lower limits of quantification.
Herein, dierent amounts of bentonite, silica–calcium fertilizer and zeolite powder were applied in a typical Cd-contaminated paddy eld in southeast China for 3 years to investigate the e˜ects ...
The microwave RL of the silica sand layer was studied over the moisture content of 1% to 5% at 20°C and the silica sand (5% moisture content) in the temperature range of 20 to 100°C at 2.45 GHz.
This study reveals that the liquid limit, plastic limit, dry unit weight and optimum moisture content of bentonite consistently increase with rise in the nanosilica …

The formation and dissociation of methane hydrates in a porous media containing silica sand of different sizes and bentonite clay were studied in the presence of synthetic seawater with 3.55 wt% salinity. The phase equilibrium of methane hydrate under different experimental conditions was investigated. The effects of the particle size of …
This article is devoted to the comparison of various methods for the quantitative determination of montmorillonite content in bentonite clays based on the adsorption of organic molecules and cations.
4.2 Compaction. A compaction test was carried out on nanosilica-mixed bentonite with the help of standard proctor compaction test. The effect of nanosilica on the compaction properties of bentonite is shown in Fig. 7a and b. Figure 7 reveals that the dry unit weight and moisture content increase with an increase in nanosilica dosage. For …
A nondestructive microwave testing method to control the green compression strength and moisture content was proposed and demonstrated. There are various green moulding sands, both qualitative (bentonite type) and quantitative (bentonite and water content), prepared. The permittivity measurements were performed by cavity …
In this study, a bentonite sample was characterized with regard to the particle size distribution, mineralogical composition and cation exchange capacity in comparison with …
