Abstract

In this paper, the test research is carried out systematically for flotation of certain hematite ore. Based on the research, we can get optimum reagent condition of flotation. The recovery rate of flotation of iron is 65.64% and the iron grade of hematite concentrate is 62.50g/t. After the flotation tailings are separated by low-intensity magnetic separator, we can also get the following results: the recovery rate is 6.72% ,and the iron grade of concentrate is 61.09%.So the final recovery rate of iron is 72.36%,and the iron grade is 62.33%.
