Abstract
Principally, mineral processing and beneficiation process on some placer mines can be considered from two points of view i.e. technical and economical aspects. Although, co-extraction of some strategic elements with high added value is conceivable, utilizing of these type of mines is also possible as raw material and feed in ferrous and non-ferrous metal industry. In this research, feasibility study of placer mine beneficiation for co- extraction of strategic elements and Iron has been investigated. Firstly, mineralogy, chemical properties and physical properties of samples have been studied via different characterization methods such as: screening, XRD, XRF, OM and EPMA analysis. Furthermore an appropriate process has been designed by using the gravity separation, ball mill grinding and magnetite separation in order to achieve suitable fineness for iron, titanium and vanadium concentrates. The designed process is capable of producing the ore concentrate with approximate 57 wt% Iron, 8 wt% TiO2 and 0.8 wt% V2O5. The outcome of the aforementioned process is valuable since it has been shown in the literature that the extraction of vanadium can be completed by leaching process with hot water and separation of titanium can be achieved during the melting process of iron from the slag.
