Removal of Silica and Alumina as Impurities from Low-Grade

Extraction of iron from Sanje ore by single stage magnetic separation or flotation process did not produce high grade iron concentrate with silica and alumina content. This is because Sanje ore has iron mineral particles which are strongly aggregated with silica and alumina and disintegration using single separation technique was difficult.
