Abstract
Anhui hematite contains 43.21% of iron and 30.11% of silicon; it belongs to high silica refractory hematite. In this paper, reverse-flotation process was adopted to deal with the ore; as a result, good indexes can be obtained, which the iron concentrate grade is 61.76 % with 83.06% recovery. Flotation process can be carried out at room temperature, in comparison with anionic reverse flotation process, cationic reverse flotation can reduce the cost of ore processing. study.
