Feb 03, 2019 Although the phosphate resources in China are abundant, they mainly consist of low-grade phosphate rock. The beneficiation of low-grade phosphate ores is also a worldwide problem, and effective technologies to process such ores are yet to be developed. As a result, most low-grade phosphate rocks are currently unexploited.
Large unexploited reserves of low grade rock phosphate in many countries are unsuitable for manufacture of phosphatic fertilizer. For industrial use of these low grade ores, a need arises to beneficiate them up to required phosphorus content 30. The floatation processes of beneficiation
process of beneficiation of RP. Hence more efforts can be applied to improve the performance of low grade RP, since it is available locally in large volumes. Despite the earlier researches, to the best of our knowledge, relatively sparse data currently exist in terms of addition of inorganic nitrogen fertilizers to low grade RP. Thus,
