The device used to separate minerals based on their magnetic properties is called a Frantz Isodynamic Magnetic Separator. The magnetic separator consists of a large electromagnet through which mineral mixtures can be passed on a metal trough which is divided near its exit end.
All forms of mineral separation suffer from one difficulty. It is impossible to completely eliminate impurities. Depending on what the impurities are, that may or may not be a major problem.
For example, if you were separating hornblende from a granite for Zr analysis, potential contamination by zircon inclusions in the hornblende might be a major problem. The different types of membranes the team is using are ceramic, polymeric, or composite, mainly in the microporous range.
They are currently in the process of testing different magnets at varying configurations around the membrane, as the geometric configuration of the magnets and the magnetic field properties influence the transport behavior of the targeted chemicals.
Karanikolos reports that discussions will be carried out for large-scale testing and integration with support from GASCO. Through this research project, Dr. Karanikolos and his team are contributing key scientific insights to the advancement of chemical separation methods that could drastically reduce the high energy cost of current thermally-driven separation processes.
Such innovations could not only provide high-priority UAE industries with an important competitive advantage, but also help reduce the global carbon footprint. Related Articles. Manor, Patrick J.
