Modern iron ore processing: challenges and solutions from ALLMINERAL

Abstract

This article describes current technologies and their application to various types of iron ores characterized with different material composition. The data presented demonstrate specific advantages of the Alljig jigging machine used in iron ore processing due to the precise separation with high density as well as the ease and low cost of operation. The Allflux hydroclassification technology ensures high output and yields three products. The Allgauss high intensity magnetic separators for slightly magnetic particles offer high throughput rates combined with unparalleled process flexibility and two-stage processing in a single plant. The Allflot pneumatic ejector flotation chambers can half the equipment footprint of the processing plant, while increasing the recovery of fine particles by reverse flotation. Technological performance indicators of the ArcelorMittal jigging machines are provided (CIS).
