Bentonite - Wikipedia

The main uses of bentonite are in drilling mud and as a binder, purifier, absorbent, and carrier for fertilizers or pesticides. As of around 1990, almost half of the US production of bentonite was used as drilling mud. Minor uses include as a filler, sealant, and catalyst in petroleum refining. Calcium bentonite is sometimes marketed as fuller's earth, whose uses overlap with those of other forms of bentonite. Bentonite is used in drilling mudto lubricate and cool the cutting tools, to remove cuttings, and to help pr

11.25 Clay Processing

Bentonite - A flow diagram for bentonite processing is provided in Figure 11.25-5. Mined bentonite first is transported to the processing plant and stockpiled. If the raw clay has a relatively high moisture content (30 to 35 percent), the stockpiled material may be plowed to facilitate air drying to a moisture content of 16 to 18 percent.

Bentonite Minerals Technologies Inc.

Bentonite. Bentonite is the common name for naturally occurring clay that contains the active montmorillonite mineral. The special properties of montmorillonite that enable commercial applications include the sub-micron platelet structure, very high surface area (≈ 800 m 2 /g), and inherent negative charge in the platelet that is counter balanced by exchangeable cations.

Bentonite - Earth Resources

Bentonite is a clay consisting mainly of smectite minerals, commonly formed by decomposition of volcanic ash or tuff, or sometimes from other igneous or sedimentary rocks. Bentonite is a very plastic clay that shrinks (or swells) markedly in response to the removal (or addition) of water. There are three main types of bentonite: high swelling ...

Wyoming Bentonite

Bentonite Production History. The first bentonite production, at $25 per ton, was in 1888 by William Taylor from a property near Rock Creek. From 1888 . through 1895, Taylor shipped 5,400 tons of bentonite from the quarry to buyers across the country. The price remained stable until 1896, when purchasers refused to pay more than $5 per ton.

Glass casting - Wikipedia

Modern techniques Sand casting. Sand casting involves the use of hot molten glass poured directly into a preformed mould. It is a process similar to casting metal into a mould. The sand mould is typically prepared by using a mixture of clean sand and a small proportion of the water-absorbing clay bentonite. Bentonite acts as a binding material.
