| Abstract: | Magnetization roasting gravity separation magnetic separation test was carried out on a Limonite tailings in Laos. Based on the study of process mineralogy, the tests of roasting, magnetic separation and gravity separation with different particle sizes were carried out, and the multi process comparative tests were carried out; The beneficiation process suitable for the mine was studied. Roasting shaking weak magnetic separation was adopted, and the indexes of concentrate yield 42.95%, iron concentrate grade 62.10% and recovery 45.73% were obtained. |
