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 construction …
We obtained the same results with coal-quartz-bentonite dust mixtures in vitro. Our experiments show that comparison of the biological effects of artificial dust mixtures and airborne dust samples is justified, and prove that performing various examinations simultaneously give fuller particulars on the probable biological effect of mineral ...
The overall approach focuses on solving the agglomeration problem of explosive bentonite in a humid coal mine environment and manufacturing a highly dispersible modified explosive bentonite material that can maintain a certain degree of dispersion under such conditions.
Dry bentonite sealants have become very popular because they are easy to apply and require no mixing or pumping. They are a very effective method of grouting wells and other boreholes with a high-solids bentonite seal. They actually provide the highest solids bentonite seal available today.

In general, with bentonite cement slurry densities are from 11.5 to 15.0 ppg. Bentonite can be mixed in two ways. It can be directly mixed with cement (dry-blended) and later the blend is mixed with water/mix water/mix fluid or it can be mixed in the mix water (pre-hydrated) and later cement is added in the mixed fluid.
The coal dust samples were airborne samples collected by means of a cyclotron in the mines of Mecsek (Hungary). The particle size of the airborne fraction was less than 5,m. The dust mixtures-quartz-bentonite, quartz-coal and coal-quartz-bentonite-were prepared from the above mentioned samples, just before the distribution of the cells.

Compacted landfill liners are required to minimize the migration of harmful contaminants to the surrounding geoenvironment and groundwater. This is mainly achieved by restricting hydraulic conductivity of the compacted liners within a permissible limit of 10−7 cm/s. For geomaterials used in liners, it is important to determine the appropriate range …

Commodity Description. Bentonite is a type of clay rock that is widely used in industrial processes and products and in consumer products. When wetted it holds water and swells significantly and, upon drying, it shrinks significantly. When mixed with sufficient water to create a slurry it forms materials that become more solid when compressed.
The dust from glaze materials is harmful to the lungs and avoiding dust clouds is a good studio practice. ... (I mixed dry bentonite in with the other dry ingredients and then added all the dry ingredients to water and let it sit before I sieved it.). I could hardly sieve it–it was so thick. This is less than 1% bentonite in the glaze–not ...
