Methods of iron ore desulfurization

Abstract

The article presents information on raw material resources and iron ore production worldwide. Kazakhstan is among the world's top ten iron ore-producing states. As high-grade iron reserves become exhausted, ores with low iron content and high impurity levels, including sulfur, are increasingly being processed. Various methods of iron ore desulfurization are discussed: flotation, magnetic, and combined approaches based on pyro- or hydrometallurgical processes that alter the chemical composition of the feedstock. The review provides information on methods for beneficiating low-grade iron ore and their significance for the development of iron and steel metallurgical production.
