Research shows increased iron ore concentrate enhances briquette strength and density, suggesting viability for metallurgical applications.
The article presents the results of research on the briquetting of finely dispersed dust (FDD) from ferroalloy production using iron ore concentrate. The obtained results indicate that increasing the iron ore concentrate content in the briquetting charge up to 15% contributes to an improvement in the strength and density of the briquettes. The composition of the resulting briquettes corresponds to that of FeSi50-grade ferrosilicon, allowing them to be used as a substitute for standard FeSi50. The proposed method for processing fine dust waste, considering the large reserves of FDD and the simplicity of the initial charge composition, demonstrates promising potential for waste utilisation and the subsequent application of the obtained product in the metallurgical industry.
