Comprehensive Study upon the Application of Rare Earth Magnets in Mineral Processing by using osmium nano particles

In this letter, the important role of rare earth magnets in mineral processing has been investigated. We know very well that New advances in permanent magnet technology have led to the development of a new generation of permanent rare earth industrial magnetic separators[1-3]. The excellent separation efficiency of these rare earth magnetic separators has resulted in elevation of super processing conventional electromagnetic high-intensity magnetic separators for many applications [4]. One example of this technology is the osmium nano particle magnetic separator which has been successfully installed for mineral processing applications. Also, in this letter, utilizing the Osmium nano particles in a novel application of removing ash and pyritic sulfur from coal samples is presented. In this work, we are investigating new applications for high-intensity permanent magnetic separators.One obvious point is the reduction of ash and sulfur contents of coal. Pass over the Osmium nano particles unit[5,6]. Useful reductions in the sulfur content of the smaller size fraction were also achieved .It can be seen that a significant reduction in ash has been achieved in the smaller size fraction after one pass over the Osmium nano particles unit. Useful reductions in the sulfur content of the smaller size fraction were also achieved.
