Title: Research on Improving the Classification-Gravity Concentration Technology Based on an Anshan-Type Low-Grade Hematite Ore
Abstract: The beneficiation of Anshan-type low-grade hematite ores attracts more and more attention. Complicated beneficiation flow sheets are necessary to deal this type of ores. Classification-gravity concentration technology is used widely in these flow sheets because of its characteristics. In this paper, grinding characteristics and classification-gravity concentration tests were carried out based on the ore’s mineralogical characteristics. When the ground size of the ore was 75% -0.071mm, through beneficiation by the flow sheet of classification-gravity concentration-middle intensity magnetic separation discarding, a satisfactory concentrate assaying 67.58% Fe, 47.51% recovery was obtained, and the iron grade and yield of the tailings were 5.93% and 39.77% respectively. The controlling of the size distribution and the behavior of finer hematite grains is important and efficiency in beneficiation of Anshan-type hematite ores.
