%X The reduction roasting and weak magnetic separation techniques were adopted to recover high grade iron-rich ore from blast furnace sludge, and in the roasting process, CH3COOH solution was used to reclaim zinc in a by-product of Zn(CH3COO)2. The optimum conditions were obtained as follows: temperature 1373.2 K, and time 60 min. Through the reduction roasting, the dezincification rate reached up to 98%, a high grade iron ore with only 0.04% zinc was obtained. By weak magnetic separation 80% iron rich ore was...
