Floatability studies of wavellite and preliminary results on phosphorus
However, the phosphorus removal from iron ores other than igneous formations has been a challenge for most of the iron ore operations. This research aims to make a preliminary study of wavellite's floatability and to evaluate the reduction of phosphorus content by froth flotation from a Brazilian iron ore with a P content of 0.82%.
