| Abstract: |
| It has an iron content of about 35% in the middlings of Yuxi Dahongshan Mining CO.,LTD, in which hematite and Magnetite are fine embedded, and they are generally packed by the gangue minerals. In order to comprehensively recovery them, reverse flotation tests were carried out, the closed test obtained an iron concentrate with the iron grade of 52.58%, and the iron recovery of 89.00%, the mineral processing index was good. |
