Abstract
In this study, enrichment possibility of apatite-bearing iron ore sample was investigated to obtain iron and phosphate concentrates, separately. It was determined that the raw iron ore contains 35.75% Fe and 5.36 P2O5. Magnetite from the ore can be enriched with low field strength wet magnetic separators, and apatite can be enriched from magnetite residues by flotation. For this purpose, the raw ore was ground to minus 106 m size and then subjected to magnetic separation and following flotation. According to experimental result, a magnetite concentrate containing 63.55% Fe and 0.65% P205, and a phosphate concentrates containing 25.33% P2O5 and 6.45%Fe were obtained. The results show that there are still difficulties in obtaining low iron-containing apatite concentrate. It is concluded that it is difficult to separate the iron and phosphorus minerals from each other, probably due to complex mineralogical composition and poor mineral liberation of the ore.
Highlights
With the developing industry and technology in the world, the demand for iron and steel is increasing continuously
It was demonstrated that sodium silicate could be used as a dispersant of slime and as depressant and activator for Characterization techniques: Crystallinity of the samples was determined by X-ray diffraction analysis (XRD) using Rigaku RadB type diffractometer
The results show that low-grade iron ore can be enriched by magnetic separation
Summary
With the developing industry and technology in the world, the demand for iron and steel is increasing continuously. Reserves of high-grade iron ore, that can be used directly in the iron and steel industry, are limited and are getting depleted very fast. It has become essential to prepare the iron concentrate to meet the specification of the steel industry. Physical methods such as gravity concentration, magnetic separation and flotation are standard practices to separate the gangue minerals from iron ores. The ores having ferromagnetic nature are suitable for being processed using magnetic separation methods [1]. Magnetite (Fe3O4) is the most ferromagnetic of all the naturally occurring minerals on earth, and low-intensity magnetic separators are widely used to upgrade magnetite ores
