The article investigates the application of bentonite-polymer composites (BPC) in the process of granulation of iron ore concentrates to increase the strength and stability of iron ore pellets. The purpose of the study was to optimize the physical and mechanical properties of the pellets using BPC as a binder. The relevance of the work is associated with the growing demand for more efficient pelletizing technologies capable of ensuring high-quality pellet production while reducing binder consumption and improving process stability. During the experiments, laboratory tests were performed with various dosages of bentonite and BPC, achieving a stabilized granulometric composition and improved strength characteristics of green pellets. The results showed that BPC added to the batch promoted a significant increase in compressive strength and a decrease in the abrasion of calcined pellets. In addition, binder consumption was found to be connected with the quality indicators of the product, enabling the optimization of the technological process and the achievement of target parameters. The paper stressed the importance of using high-quality binders to improve pellet efficiency and stability, which has significant implications for metallurgical production. Recommendations for the use of BPC can be applied in the development of new methods for the production of iron ore pellets with improved performance.
