| Abstract: | An iron-separation tailings containing Fe 28.04% is the overflow in the washing processing and its size is really fine.This paper studied on the iron recovery of the tailings.The combination experiment flow of ore pulp dispersion,magnetic separation and floatation was adopted after Comparing with several schemes.The closed-circuit testing is as following： the iron concentrate grade is 58.77%and the iron recovery rate is 68.58%.So it makes the tailings be used comprehensively and improves the enterprise with economic and social benefits. |
