  • Processes for phosphorus removal from iron ore a review

    Yi et al. investigated the reverse flotation of oolitic iron ore from Hubei, China region, previously subjected to a reductive calcination and were able to obtain a concentrate with 60.14% Fe and 0.22% P. They concluded that the result is more effective than when using flotation, in ore, without treatment.
