The Beneficiation Techniques for 5 Types of Iron Ores

2020-12-7  The global professionals of iron mine beneficiation have been doing the research work of removing sulfur and phosphorous from iron ore. The experiment shows that the highest grade of iron concentrate can be obtained by the process of stage grinding → high-gradient strong magnetic separation → discarding tails → flotation to remove phosphorus → reverse flotation.
