: The flotation of pure and natural carbonaceous iron ore samples in the oleate flotation system was investigated. Starch can depress hematite effectively in a wide pH range, but cannot depress... for treating these carbonaceous iron ores. In this work, the floatability of three pure minerals (hematite, siderite and quartz) in sodium oleate flotation system was investigated and the effect of siderite......
