Listing description
Also known as potash bentonite or K-bentonite, potassium bentonite is a potassium-rich illitic clay formed from alteration of volcanic ash.
Detailed description
Uses
The
main uses of bentonite are for drilling mud, binder (e.g. foundry-sand bond,
iron ore pelletizer), purifier, absorbent (e.g. pet litter), and as a
groundwater barrier.[2]
As of around 1990, almost half of the US production of bentonite was used for
drilling mud.[2]
Drilling mud
Bentonite
is used in drilling fluids to lubricate and cool the cutting
tools, to remove cuttings, and to help prevent blowouts.[2]
Much of bentonite's usefulness in the drilling and geotechnical engineering
industry comes from its unique rheological
properties. Relatively small quantities of bentonite suspended in water form a
viscous, shear thinning material. Most often, bentonite suspensions are also thixotropic,
although rare cases of rheopectic behavior have also been reported.
At high enough concentrations (~60 grams of bentonite per litre of suspension),
bentonite suspensions begin to take on the characteristics of a gel
(a fluid with a minimum yield strength required to make it move). For these
reasons it is a common component of drilling
mud used to curtail drilling fluid invasion by its propensity for aiding in
the formation of mud cake.
Binder
Bentonite
has been widely used as a foundry-sand bond in iron and steel foundries. Sodium
bentonite is most commonly used for large castings that use dry molds, while
calcium bentonite is more commonly used for smaller castings that use
"green" or wet molds.Bentonite is also used as a binding agent in the manufacture of iron ore (taconite) pellets as used in the steelmaking industry.
