Bentonite is the name used for a range of clays that can swell and gel when dispersed in water. The name "bentonite" originates from the discovery of this type of clay near Fort

Hematite is the mineral form of iron(III) oxide (Fe 2 O 3), one of several iron oxides. Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum. Hematite and ilmenite form a complete solid solution at temperatures above 950 °C (1,740 °F).

Baryte or barite (UK: / ˈ b ær ʌ ɪ t /, / ˈ b ɛər aɪ t / [citation needed]) is a mineral consisting of barium sulfate (Ba S O 4). Baryte is generally white or colorless, and is the main source of baryte group consists of baryte, celestine (strontium sulfate), anglesite (lead sulfate), and anhydrite (calcium sulfate). Baryte and celestine form a solid solution (Ba,Sr)SO 4.

Uses of Bentonite in Construction. The recognition of bentonite as a vital construction element is still in its latent stage, since a hefty percentage of foundations and other civil engineering activities are still carried out without using bentonite and are incurring much higher expenditure through use of .

Bentonite slurry is one of the most common excavation fluid used in constructing diaphragm wall. Bentonite clay (in powder form) and water are combined in a colloidal mixer and clay particles bond to each other and set to form a gel when left to stand for a period of time.

Wyoming bentonite is shipped all over the world for use by professional drillers and others. One of the special properties of bentonite is the way it quickly swells to as much as 10 times its original volume when it is completely mixed with water. When bentonite .

Besides, very low magnetism does not favor easy separation of hematite from aqueous solutions. Instead, the polymorph of hematite such as maghemite (γFe 2 O 3) and reductive phase of hematite such as magnetite (Fe 3 O 4) demonstrate much higher magnetic property and enhanced Cd 2+ and Cu 2+ removal capacity (Chowdhury and Yanful, 2013).

work focused on only three mud additives: bentonite, barite and hematite. This study focused on determining and comparing rheological properties of these mud additives. Barite (specific gravity = ~ ) and hematite (specific gravity = 5) are density control additives, while bentonite is a viscosifier.
