A method of obtaining ferric concentrate from metallurgical slag
Original language description
A method of obtaining ferric concentrate from metallurgical slags from steel production, containing at least 10% by weight Fe, consists of gradually crushing and grinding them into granules with a maximum grain size of 1.0 mm and then magnetically separating the magnetic fraction contained in the granulate, the granulate is mixed with water in a ratio of 1 wt. part of granulate per 10 to 100 wt. parts of water to obtain a easily mixable suspension, which, after mixing, is continuously stirred for 2 to 30 min. magnetic separation with the simultaneous interaction of 20 to 40 kHz ultrasound . The magnetic fraction obtained by magnetic separation is then dried to a constant weight to form a ferric concentrate with a content of 20 to 80% by weight of Fe. The granulate can be calcinated at 600 to 1000oC for at least 60 minutes before mixing it with water. To increase the efficiency of this method, the residual portion not captured by magnetic separation can also be calcinated under the same conditions, which, alone or in a mixture with new granulate after mixing with water, is repeatedly magnetically separated under the simultaneous action of ultrasound.
