Al impurity, the floatabilities of hematite and aegirine were resemble, which is contributed to the existence of structrual iron ion on surfaces of both minerals. It is the structrual iron ion that accelerates the floatability of aegirine greatly and leads to difficult separation with hematite. 2. The basic mechanism of actions of fluorosilicate salts as selective depressants of aegirine during the direct flotation of hematite was investaged detaily by using FTIR and XPS spectrocppy, fluorosilicate salts are poor depressants for hematite, but are very strong depressants for iron-containing silicate such as aegrine in weakly acid medium, which can enlarge the flotation differences between two minerals.
