Recovery and separation of phosphorus as dicalcium phosphate

One possible use is as a low grade iron ore, i.e., while the iron content (7.8–22.4 wt% iron) is considerably lower than that of typical iron ores, the primary impurity components are magnesium and calcium, which are typically mixed with iron ore as fluxing agents in blast furnace operations. The obtained precipitate could potentially be sold as an ore-flux mixture.احصل على السعر
