Abstract

Natural minerals, such as bentonite, kaolinite, biotite, vermiculite, and glauconite, which have sufficiently high performance properties in the softening of industrial and waste water, softening and cleaning of heavy metals, are promising. To study the physical and chemical properties of glauconites from various deposits of the country, samples of glauconite mineral were brought from the Parkent, Bukhara, and Karakalpak mountain reserves, their physical and chemical properties were studied, compared with each other, and the optimal reserve was selected. The reserves of these deposits are sufficient and have the potential for industrial development. The purpose of this study is to compare samples of natural mineral reserves of glauconite and select the optimal deposit for raw materials.

Methodology. Samples of glauconite minerals from the Parkent, Bukhara and Karakalpak mines were taken as the object of the study. Chemical, mineralogical, and thermal analyses were performed on the samples, and the fractional composition was determined.

Scientific novelty. The main part of the mineral glauconite (50-55%) in the raw material is found in fractions of 0.08-0.125 mm. The most suitable raw material was the Parkent glauconite deposit, which has a relatively high content of potassium, which tends to exchange with other metals during the sorption process.

The received data. Based on the conducted experiments, samples of glauconites from Parkent, Bukhara, and Karakalpak were subjected to chemical and mineralogical analyses. The maximum amount of the mineral glauconite was found in the fractions of the raw material (less than 0.125 mm). The most suitable deposit of raw materials for processing the mineral glauconite was selected and an environmentally friendly adsorbent was obtained.
