Recovery Rhenium from roasted dust through super Para-magnetic Nano-particles

• In this research, modern, fast and cost effective solutions based on Nano-technology are presented to produce Rhenium.
• Up to now several methods have been presented among which absorption process is so attractive for its simple and effective design and simple function. Absorption process is expected for magnetic absorbents with high capacity and simple separation. According to results of ICP analysis, Rhenium absorption was %82.
• Washing the Nano-absorbent after recovering Rhenium ions from Nano-particles makes it prepared for further operations.

Rhenium, a valuable and rare metal, is a byproduct of Molybdenum. It is usually produced through the dust and smoke of roasting Molybdenum concentration. Heat roasting is the traditional method of producing Molybdenum from sulphuric resources (Molybdenum), which not only creates environmental problems but also wastes some of the existing Rhenium.To produce Rhenium, in this research, a Nano-technology-based solution is presented which is modern, fast, and economical. Rhenium, classified among the external mediator elements, is in group 7 of the periodic table. Regarding the arrangement of Rhenium's electron layer capacity, i.e. 5d5, its d orbital is completely sub-saturated and therefore, equipped with magnetic characteristic. As such, Rhenium can also be considered as a Para-magnetic metal. In this research, after providing metal ions solution, the absorption of Rhenium ions is examined under different operational conditions through the super Para-magnetic Nano-particles of Fe3O4, which helped to determine the best conditions for absorption to occur. Washing the Nano-absorbent after recovering Rhenium ions from Nano-particles makes it prepared for further operations.
