| Abstract: | Through the replacement of magnetic matrices in industrial test, which proved that the optimized 1.5mm and 2mm mixed magnetic matrices is better for the separating effect of micro fine difficult selection hematite ore, the recovery increased by 10% and the metal recovery rate has increased by 1.3% for raw ore. The -325 mesh fraction in tailings decreased by an average of 5% and with an increase of 23.81 million per year for the company. |
