METHODS OF PELLETIZING FINE CHROMIUM RAW MATERIALS, KEMPIRSAY DEPOSIT, USING POLYMERIC BINDER

https://doi.org/10.48498/minmag.2023.221.9.001

This article describes the existing methods of pelletizing crude ore materials. Their main methods and mechanisms have been considered. The technologies of formation of briquettes and brexes have been described in detail. In the work, fine chromium raw materials from Kempirsay deposit are used as materials under study. The material is a loose substance obtained after drying chrome ore. The chemical and particle size distribution composition of fine chromium raw materials is given. The binder is polyacrylamide. A comparative analysis and differences between the methods of pelletizing have been carried out. The methods of pelletizing have been described, and the results of laboratory research on pelletizing have been obtained. The qualitative indicators of the obtained pelletized products were evaluated. The recipe for the optimal composition of the mixture for pelletizing has been selected. The factors affecting the quality of briquettes and brexes have been determined.
