EXPERIMENTAL RESEARCH ON THE COMPREHENSIVE RECOVERY AND UTILIZATION OF SPECULARITE ORE

On the basis of original technique and experimental research, the beneficiation process of weak magnetic-high intensity magnetic-shaker grading is adopted to make full use of the abundant specularite resources in mining area. Under the conditions of 95.10% for final grinding fineness of -0.075 mm, the test results in comprehensive iron concentrate with a yield of 29.46%, grade of 68.19% and recovery of 58.98%, as well as micaceous iron oxide product with a yield of 12.73%, grade of 68.89% and recovery of 25.75%.
