In China, direct-reverse flotation is proved to be applicable to most phosphate ores. However, because the ratio of froth product is generally high, current direct-reverse technology faces challenges in terms of high reagent consumptions and cost. A new gravity and flotation combined process has been developed for the recovery of collophanite from sedimentary phosphate ore from the

Application of biotechnology in iron ore beneficiation

2015-1-1  Williams and Cloete (2010) determined that A. niger produced citric acid to solubilize approximately 23% of phosphorus from an iron ore concentrate, which was similar to that reported by Delvasto et al. (2005), who found that a strain of A. niger (isolated from a high-phosphorus Brazilian iron ore) removed 20% of phosphorus rendering it acceptable for processing.
