A method for iron concentrate recovery from alumina red mud

Page view

The technical scheme of this invention: first recovering strong magnetic Fe concentrate by mediumintensity magnetic separator after alumina red mud tailings residue separation, the obtained tailings through the open roughing and cleaning of high gradient magnetic separator to recover weak magnetic Fe concentrate, mixing the above strong and weak magnetic Fe concentrate, then the Fe concentrate can be produced after dewatering.
