| Abstract/Notes | Titanium (Ti) and vanadium (V) are metals critical for the sustainable development of our society. Their growing demand and the depletion of ores rich in these metals along with technological development lead to a reconsideration of sources that were previously considered unpromising. The present work is devoted to the study of an iron (Fe) ore from southeastern Bulgaria, containing Ti and V in low but potentially recoverable concentrations. The aim was to check whether it is possible to obtain an iron concentrate containing Ti and V in concentrations comparable to those in similar market products. The material was examined by optical microscopy, XRD, SEM-EDS, and ICP MS. Magnetic separation was applied with and without predating gravity separation. By applying wet gravity beneficiation followed by a low-intensity magnetic field, an iron concentrate (40%–65% Fe) bearing 3%–5% Ti and 0.4%–0.59% V was obtained. Using only a low-intensity magnetic field, without gravity separation, an iron concentrate (59.4% Fe) containing 3.5% Ti and 0.44% V was obtained. Vanadium was extracted in the highly magnetic material, while a significant amount of Ti was left in the weak magnetic fraction. An additional 1.5% may be recovered by applying a high-intensity magnetic field. The main processing challenge appears to be the recovery, without flotation beneficiation, of magnetite that is oxidized to non-magnetic hematite and maghemite. Using magnetic separation (with or without preliminary wet gravity beneficiation) avoids pollution of the processing waste with reagents. Thus, the waste from the beneficiation of the studied type of ore can be used as a soil improver. As a result, the extraction of critical metals using a practically waste-free technology may be achieved. |
