Study on Bioleaching of Sulfur in Iron Ore by Mixed

Jan 01 2015 Shen et al 2012 also found that acidophilic bioleaching microorganisms effectively bioleach phosphorus from iron ore when they added highphosphorus iron ore and elemental sulfur to municipal wastewater to make an iron ore slurry Apatite was the main phosphorus mineral in the iron ore and the wastewater contained native sulfuroxidizing bacteria What Is The Phosphorus In Iron Ore Sovica Iron Ore Definition Of Iron Ore And Synonyms Of Iron The typical magnetite iron ore concentrate has less than 01 phosphorus 37 silica and less than 3 aluminiumThe grain size of the magnetite and its degree of commingling with the silica groundmass determine the grind size to which the rock must be comminuted to enable efficient magnetic
