اقرأ أكثرIt utilizes significantly finer magnetite (about 5 micron mean particle size), as compared to normal mean particle sizes of 10-20 microns. It can effectively beneficiate coal particles down to 30 microns in size, as compared to the most advanced, existing conventional systems that are limited to a particle bottom size of about 150 microns.
اقرأ أكثرFine magnetite mixed into a water suspension is commonly used in coal preparation to create a pseudo- specific gravity great enough to effect separations between coal and associ- ated impurities. The magnetite must not only be reclaimed but must also be cleaned to prevent coal and impurities from building up in the washing cir- cuit.
