type: item
description: The use of clay powders with sorption properties worldwide is largely hampered due to difficulties in the development and delivery of these adsorbents from industrial quarries to regeneration plants. However, their widespread use is due to the lack of effective methods of their processing and the limited ability to activate the upper part, currently, instead of an expensive clay powder adsorbent, a method for obtaining a local cheap activated adsorbent has been determined. It was analyzed that it can replace expensive imported sorbents that are used due to the fact that not enough experiments have been conducted to study their composition.

description: The study of the influence of various modifiers and other factors on the flotation of the studied ores from the lower horizons of the Dzhizhikrut deposit revealed the feasibility of using a simple scheme for this ore to obtain antimony concentrate. Based on the research carried out, a technological scheme for flotation of ore from this deposit is proposed. The article also examines the atomic-molecular structure of the flotation products of gold-antimony-mercury ores based on X-ray scattering. These products were analyzed on a high-tech general purpose X-ray diffractometer DRON-3.
