The methylene blue capacity of a drilling fluid indicates the amount of reactive clay (e.g., bentonite or drill solids). The methylene blue capacity provides an estimate of the total cation exchange capacity of the drilling fluid solids. Methylene blue capacity and cation exchange capacity are not necessarily equivalent. Usually,

The surface area of bentonites can only be calculated with methylene blue adsorption when the montmorillonite surface area per charge corresponds with the area of the methylene blue cation of 130 Å 2, i.e. the interlayer charge of the montmorillonites must amount to 0.28–0.33 charges per half unit cell. Our investigations have confirmed the ...

This chapter discusses the commonly used tests to evaluate bentonite samples which include drilling fluid products, foundry products, iron ore pelletizing.

Bentonite is a non-metallic mineral with montmorillonite as its main mineral component and its content is 85-90%,the hardness is 1-2 and the density is 2-3g/m³,because of the change of iron content.there are different kinds of color,like White, light yellow, light grey, light green, pink, brown red, brick red, grey black etc..

Redmond Clay is a pure, bentonite clay that we mine ourselves, not too far from our salt mine near Redmond, Utah. Deposited many years ago as the ash of now-inactive volcanoes, it's unique in that it contains both calcium and sodium. It also includes a blend of natural, beneficial trace minerals. We gather it from the earth, crush it into the powder, and put it in a jar or bucket …

This International Standard specifies a method for determining the water absorption of bentonite. The bentonite component is a part of clay geosynthetic barriers (GBR-C).

This standard keeps in view the quality of bentonite available and as is being commercially exploited in the country by the ceramic industry as a whole. The following Indian Standards on bentonite have already been published: a) IS 6186 : 1971 Specification for bentonite b) IS 10214 : 1982 Methods of sampling bentonite

When heated to 600℃, the blue absorption and colloid value of bentonite decreased sharply, and the hydroxyl groups in the main component montmorillonite octahedron sheet began to break out, while the layered structure was damaged. The montmorillonite phase disappeared above 800℃. A new mineral phase cordierite was produced at 1000℃.

ISO 10769:2011 specifies a method for determining the water absorption of bentonite. The bentonite component is a part of clay geosynthetic barriers (GBR-C). Water absorption depends on the specific surface of the fine particles and the surface activity of the bentonite. The test provides an index value for production control testing of GBR-C.
