Physiochemical separation of iron ore
The two major aluminum-containing minerals in iron ore are kaolinite (Al 2 (Si 2 O 5 ) (OH) 4) and gibbsite (Al (OH) 3 ). Some progress has been made in using flotation to separate kaolinite from hematite. High levels of phosphorus in iron ore attract a penalty because this makes steel brittle.
