The application of coalbased reduction in the efficient recovery of iron from refractory ironbearing resources is comprehensively reviewed. Currently, the development and beneficiation of refractory ironbearing resources have attracted increasing attention. However, the effect of iron recovery by traditional beneficiation methods is
Coalbased reduction followed by magnetic separation is a promising technology for processing refractory iron ores. Analysis of the size distribution of metallic iron particles is an effective approach for exploring the mechanisms of coalbased reduction. As metallic iron particles exhibit very complex shapes compared with nature ores,
The subsequent magnetic separation of Fe Si alloys from the reduced product has not been systemically studied. It is well known that magnetic separation is a promising method to separate magnetic particles. However, the mechanism for separating magnetic particle from the minerals would be complex, which generally involves a lot of influencing
With coal having a diamagnetic susceptibility of 0.6 x 108 kg1 magnetic separation would prove very difficult. We have, nonetheless, achieved a 43 % reduction in total sulphur using a small laboratory highgradient separator. It is against this background that the magnetic measurements on coal were undertaken. 00223727/80/040067+04

The OpenGradient Magnetic Separation (OGMS) technique can separate particles on the basis of small differences in magnetic susceptibility. The highly reactive coal macerals are diamagnetic while the minerals and less reactive macerals range from slightly diamagnetic to paramagnetic with the pyritic minerals exhibiting the greatest positive magnetic

Inorganic sulfur and ashforming mineral matter have been removed from solventrefined coal by high gradient magnetic separation at temperatures up to 587°F. Reduction in sulfur and ash content is temperature dependent and is correlated with the H/v ratio.
Fly ash from three coalburning power plants in Bulgaria: 'Maritza 3', 'Republika' and 'Rousse East' were subjected to wet lowintensity magnetic separation. The tests were performed at different combinations of magnetic field intensity, flow velocity and diameter of matrix elements. It was found that all parameters investigated affected the

High Gradient Magnetic Separation (HGMS) has been successfully applied to the removal of pyrite from water slurries of raw coal in bench scale tests in several laboratories. Dry processing is more difficult but some advances have been reported. Coalmethanol slurries offer promise. HGMS has also been successful in filtering out particulate inorganic sulfur
