Beneficiation Experiments of Iron Improvement and Sulfur Reduction for a Magnetite Mine

Abstract

Abstract: Due to the uneven ore blending of a Guangdong magnetite ore, substandard iron concentrate with low Fe grade and high content of sulfur often appears. So the beneficiation tests of iron improvement and sulfur reduction are made. The results show that final concentrate with Fe grade of 66.08% and sulfur content of lowering to 0.28% are obtained by adopting the process of stage grinding-stage magnetic separation-flotation for decreasing sulfur. Fe concentrate's quality is effectively improved.

Key words: Magnetic pyrite, Stage grinding and stage magnetic separation, Sulfur decrease by flotation, Iron concentrate
