quantitative leaching of a nigerian iron ore in

The gravity separation by jigging achieved an acceptable enrichment of iron concentrate, but the phosphorus was beyond the acceptable level for commercialization (less than 0.07% at that time). Acid leaching, using H 2 SO 4 , applied directly on the jig, did not get good results because of the precipitation of sulfur compounds.
