Comparative technological assessment bentonites in specific deposits Georgia and foreign countries

An assessment of the technological characteristics of bentonites from some deposits in Georgia and foreign countries was carried out. The superiority of Georgian bentonite clays in terms of basic physical and chemical indicators is shown; of the bentonites from foreign countries, the sample from Hungary turned out to be the best. The adsorption capacity of bentonites in relation to methylene blue (MB) has been studied. It has been established that heat treatment at a temperature of 500 0C leads to a decrease in the adsorption activity of bentonites towards MB.
