A process has been proposed for the treatment of apatite concentrate obtained from the dephosphoriation of iron ore. In this process the apatite is acidulated by HNO3 to produce high-purity H3PO4. The crude acid obtained is at least equivalent to if not better than the typical wet process acid. The H3PO4 is purified by extraction and concentrated by evaporation.

Processes for phosphorus removal from iron ore - a review. The composition of iron concentrate obtained 64.12 Fe and 0.07 phosphorus with an iron recovery of 96.83 and a rate of dephosphoriation of 74.08. Figure 2 shows a flowsheet for concentration by reductive sintering and removal of phosphorus.
Dephosphoriation of high-phosphorus iron ore is an unsolved problem worldwide so far. Biotechnology could be a cost-effective and environment-friendly way to solve this problem. A novel method for bioleaching of phosphorus from high-phosphorus iron ores using indigenous sulfur-oxidiing bacteria from municipal wastewaters was first reported in this work.
Picture of iron ore consumption by country is somewhat different compared to the top iron ore producing countries. Iron ore in these countries is mostly used for steel production and those top steel-consuming countries based on 2013 figures are China Japan USA.
The ore grade or concentration of an ore mineral or metal as well as its form of occurrence will directly affect the costs associated with mining the ore. The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore.
