Bentonite is also used as a binding agent in the manufacture of iron ore pellets as used in the steelmaking industry. Bentonite, in small percentages, is used as an ingredient in commercially designed clay bodies and ceramic glazes. The ionic surface of bentonite has a useful property in making a sticky coating on sand grains.

Bentonite (/ ˈ b ɛ n t ə n ʌ ɪ t /) is an absorbent aluminium phyllosilicate clay consisting mostly of montmorillonite.It was named by Wilbur C. Knight in 1898 after the Cretaceous Benton Shale near Rock River, Wyoming.. The different types of bentonite are each named after the respective dominant element, such as potassium (K), sodium (Na), calcium (Ca), and aluminium (Al).
In this work bentonite clay of different mesh sizes (75, 100, 200 and 300) were washed, dried and then activated using hydrochloric acid and sulphuric acid solution of concentrations 1.0M, 2.0M, 3.0M and 4.0M and 0.5M, 1.0M, 1.5M and 2M respectively and the bleaching capacity of the activated clay samples determined.
Bentonite clay is the main component of the water- based drilling fluid. In this study the Egyptian bentonite from (south Hammam) was tested for its potential use in drilling fluids. The drilling mud quality of the bentonite from (south Hammam) was significantly improved by using low molecular weight polyvinyl alcohol (PVA) as a viscosifier ...
Sep 30, 1975· I claim 1. A method for the activation of bentonite which comprises treating the bentonite with 0.25-10% by weight of bentonite of an organic polymer and an aqueous alkaline solution, both known, the improvement being the incorporation into the treated bentonite of an amount of 0.01-10% by weight from the pretreated bentonite of a heavy metal salt selected from salts of Fe, Ni, Zn, …
The optimum moisture of the bentonite samples for soda activation was found to be 40% in our preliminary activation studies on viscosity, swelling, and filtration loss. In soda activation, soda ash powder was added to the initially moisturized bentonite samples and kneaded till all the bentonite had reacted with soda.
The dried activated mixture was re-crushed to 250 µm and one gram was taken from the seven portions (six activated samples and one raw bentonite). The one gram aliquot was roughly subdivided into 8 sub- portions and very slowly added into a 10 ml graduated cylinder (in Figure 40: Swelling index of Na-activated 0.1 ml increments) filled with ...
Sep 24, 2015· Hi there, i would like to ask you about how to manufacture bleaching earth from bentonite? After i've read many resources that tell me the process can undergo in two ways, heat treatment or acid treatment. That's as far as i know. How about operational condition? what the best way to activate bentonite, the heat ways or the acid ways?
