1. Introduction. Iron ores used in the iron and steel industry must present a high metallic content of iron (Fe) and a low presence of contaminants, especially silica (SiO 2), alumina (Al 2 O 3), and phosphorus (P).Nowadays, China is the world's largest producer of iron ore (accounting for 45% of world's production), followed by Australia and Brazil, respectively [1].

Among them, hematite, as a weak magnetic iron ore, has uneven particle size and high content of fine particles. Hematite ore is an important iron ore resource in my country. In the early 1960s, hematite ore was mainly processed by roasting-magnetic separation and single-flotation processes, and the production technical indicators were poor.
