Abstract

Abstract: High gradient magnetic separation-flotation tests and high gradient magnetic separation-acid leaching tests were carried out on a low grade rhodochrosite ore. The results showed that through high gradient magnetic separation-flotation tests cannot get ideal index. Manganese leaching rate of 92.2% could achieved by acid leaching experiments with leaching temperature of 80 ℃, four hours length of time for leaching, S/L ratio of 5 through dealing with concentrate of magnetic separation.

Key words: Rhodochrosite, Magnetic separation, Flotation, Acid leaching
