The paper presents the results of studying the use of iron ore concentrate as a component of the charge for briquetting finely dispersed dust generated during the production of ferrosilicon. Experiments were carried out on introducing iron ore concentrate into the mixture in the amount of 3 to 10 %. Liquid glass and water were used as a binder. It was shown that the use of 5-7 % by weight of iron ore concentrate with the iron and silicon content of about 65 % and 26 %, respectively, led to increasing strength and density of the briquette by an average of 20 % compared to the same characteristics of briquettes obtained without adding iron ore concentrate. It should be expected that improving such briquette characteristics as strength and density will provide higher safety of the product during transportation and loading and better conditions during deoxidation and alloying, which ultimately ensures an improved steel quality.
