| Abstract: | The second concentractor of Kunsteel Dahongshan iron mine adopted the gravity separation process of shaking table with vibrating spiral chute in replacement of the flotation craft. It separates the high-intensity magnetic separation concentrate with Fe grade of 49.43% and SiO2 content of 16.71%. The iron concentrate with Fe grade increases to 58.71%, SiO2 content decreases to 12.32%, Fe recovery reaches 85.21%. The purpose of reducing SiO2 content, improving the Fe concentrate grade and saving costs was accessed. |
