Based on the Hydrogen Mineral Phase Transformation (HMPT), the fine grained iron-bearing manganese ore is treated. By utilizing the rich local natural gas in Zambia as energy and natural gas pyrolysis, Sanhe MPTH project with the annual processing capacity of 600,000 tons was completed in November 2020. After construction, high-quality products of iron concentrate with iron grade of 65.49% at iron recovery of 96.94% and manganese concentrate with manganese grade of 51.44% at manganese recovery of 86.45% were obtained. Based on the application of HMPT, the efficient utilization of the iron-bearing manganese ore is realized without any residue.
