Separating Pyrite & Blende Magnetism
The roast may be considered satisfactory when the separators make a recovery of from 85 to 90 per cent. of the total zinc in the raw concentrate, and yield a clean blende product carrying 1.5 to 2.5 per cent. iron due to pyrite. The iron content may, after the best work, reach a much higher figure, due to the presence of combined iron in the ...

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.
