Abstract:

The paper presents the results of research on selecting environmentafly friendly organic acids for the S-separating flotation technology in iron ore at Sin Quyền copper mine branch. The iron ore Magnetite (Fе₃O₄) received after the magnetic selection has Fe≈64%, average S content ≈3-5 %S. The results of research have selected a new reagent to adjust the pH environment, namely Oxalic Add (H₂C₂O₄), the stimuiant CuSO₄.5H₂O, the PAX aggregator and the foaming agent BK201. Iran ore products received after the fiotation JStage met the set goals. The results show that if applied to actual production, it will minimize environmental pollution, increase equipment life, improve production efficiency for the unit
