1 Introduction. Bentonite is a geological term for soil materials with a high content of a swelling mineral, which usually is montmorillonite. It is produced by in situ devitrifications of volcanic ash [].Although, bentonite chemical composition varies from one place to another place [].The bentonite clay is often extracted from open pit mines with …

A series of laboratory hydraulic conductivity ( K) experiments were conducted to assess the compatibility of a sodium bentonite paste with acid mine drainage (AMD). The K of the water-permeated bentonite was observed to be of the order of 2 × 10 –9 cm/s. Permeation of the bentonite with AMD increased K slightly by almost one order of ...
Specimens with 3% nano-bentonite showed significant improvement in unconfined compressive strength (UCS) of soil that was more than 2.3-times higher than control specimen in 7-d curing time ...
Usage of fractions is recommended when more precision is needed. If we want to calculate how many Millimeters are 20 Microns we have to multiply 20 by 1 and divide the product by 1000. So for 20 we have: (20 × 1) ÷ 1000 = 20 ÷ 1000 = 0.02 Millimeters. So finally 20 microns = 0.02 mm.
The abundance of mining activities continuously increases mine wastes/tailings that require storage/disposal. It is well understood that the accumulation of tailings around mines, and consequently, their spreading in the environment could cause serious ecological hazards. Reuse and recycling of mine tailing materials, in …
The main component of Organoclay is bentonite, a chemically altered volcanic ash that consists primarily of the clay mineral montmorillonite. The bentonite in its natural state can absorb up to seven times its weight in water, after treatment can absorb only 5 to 10 percent of its weight in water, but 40 to 70 percent in oil, grease, and other ...

The natural bentonite was purified in the laboratory to remove calcite, carbonates, and organic matters by the following protocol: the sample was first repeatedly washed with Milli-Q water and dried after each time. The dried bentonite clay (25 g) was soaked in 400 mL solution containing Na-Ac (0.1 N) and Ac-Ac adjusted to pH ≈ 5.0.
