Abstract

In this study, enrichment possibility of apatite-bearing iron ore sample was investigated to obtain iron and phosphate concentrate, separately. It was determined that the raw ore contains 35.75% Fe and 5.36 P2O5. Magnetite in the ore can be enriched with low-intensity magnetic separator, and apatite can be enriched from the non-magnetic product by flotation. For this purpose, the raw ore was ground below 106 m size and then subjected to magnetic separation (with two cleaner and one scavenger), and following flotation (with three cleaner and one scavenger). According to the experimental result, a magnetic concentrate containing 63.55% Fe and 1.65% P2O5, and phosphate concentrate containing 25.33% P2O5 and 6.45%Fe were obtained. The results show that there are still difficulties to obtain plausible iron and phosphate concentrates in terms of phosphorus and iron impurities for iron and phosphate concentrate, respectively. It is concluded that it is hard to separate the iron and phosphorus phases from each other, possibly due to complex mineralogical composition and poor mineral liberation of the ore.
