The effects of ore particle size on selectively bioleaching phosphorus (P) from high-phosphorus iron ore were studied. The average contents of P and Fe in the iron ore were 1.06 and 47.90% (w/w), respectively. The particle sizes of the ores used ranged from 58 to 3350 μm. It was found that the indigenous sulfur-oxidizing bacteria from municipal wastewater could grow well in the slurries of ...
