Abstract: In order to make a reasonable development and utilization of lean maghemite resources in a certain mine,a technological mineralogy and selectability test research was carried out for the nature and selectability of the ore at the current mining site.The test results show that the use of low intensity magnetic,high intensity magneticanion reverse flotation process can obtain a good separation index of concentrate iron grade of 68.55%,concentrate yield rate of 36.41%,metal recovery rate of 79.92%,and tailings grade of 9.86%.The selectivity of the ore is good,which provides a reliable technical basis for the rational development and utilization of the ore.

Key words: lean maghemite ore,process mineralogy,beneficiation,high intensity magnetic, reverse flotation
