iron ore contain high sulfur, phosphorus Beneficiation 

The common processes used to remove sulfur from iron ore concentrates are flotation and roasting. At the same time, the latter is costly and produces environmental pollution, so the main direction of research is to strengthen flotation.

A large number of research results prove that iron ore concentrate phosphorus removal can be used magnetic separation, reverse flotation, selective flocculation (agglomeration), acid leaching, chlorination roasting – acid leaching, bioleaching and its combined process, etc., of which magnetic separation – reverse flotation, selective flocculation (agglomeration) – reverse flotation combined process is more economical.
