Abstract

According to the properties of cyanide tailing from Lingbao, the quantitative analysis and phase analysis were chosen to define the chemical composition of the tailing and separability of Fe from cyanide tailing was investigated. The impacts of parameters on the recovery of Fe were probed to determine the optimal iron separation technological flow. The result indicated that the iron ore concentrate containing 62.69% Fe can been obtained by wet and weak magnetic separation (one roughing and two cleaning) under the optimum conditions of stirring intensity 1800r/min, stirring time 15min, roughing magnetic field intensity 63.68KA/m, and cleaning magnetic field intensity of I and II 47.76 and 39.80 KA/m separately, and a recovery ratio reached 81.78%.
