Outline
A foreign high-sulfur hematite-limonite ore contains 5.68% of sulfur and 45.95% of iron. Iron mainly occurs in hematite-limonite, and sulfur mainly exists in the form of sulfide. In order to rationally develop and utilize the ore, based on the study of the properties of the raw ore, the process flow of grinding-flotation sulfur separation-high intensity magnetic separation of iron was tested. Under the condition of grinding fineness of −0.074 mm accounting for 80%, the sulfur concentrate with sulfur grade of 41.31% and sulfur recovery of 69.74% was obtained, and the iron concentrate with iron grade of 60.84% and iron recovery of 76.92% was obtained. The sulfur content of iron concentrate meets the requirements of quality standards, and the comprehensive recovery and utilization of high-sulfur hematite-limonite ore resources are realized.
