Lower Grade Benefication Magnetite

hydrogen reduction of hematite ore fines to magnetite,surplus coke oven gases cogs and low grade hematite ores are abundant in shanxi, china. our group proposes a new process that could simultaneously enrich ch 4 from cog and produce separated magnetite from low grade hematite. in this work, low-temperature hydrogen reduction of hematite ore fines was performed in a fixed-bed reactor with a stirring apparatus, and a laboratory davis magnetic.magnetite ore beneficiation processbailing174 machinery,a 0.5 million tons per year magnetite ore production line in liaoning, ne of china. this project achieves a high ore grade by using the low intensity magnetic separation process. the grade of iron ore concentrate is 65 or more, and the comprehensive metal recovery rate is up to 85 or more, which has huge economic benefits..
