转炉尘泥磁选尾矿吸附铜离子试验研究

以某转炉尘泥的磁选尾矿为原料，研究其对铜离子的吸附效果和吸附行为。结果表明：尘泥磁尾去除铜离子的适合条件是尘泥磁尾投加量为8.0g/L，铜离子初始浓度为20 mg/L，反应时间为50 min，此时Cu²⁺去除率为97.86%。吸附行为的影响因素依次为尘泥磁尾投加量＞铜离子溶液初始浓度＞反应时间。吸附反应以表面吸附为主，伴随少量置换反应。

Study on Absorption of Cu2+ by Magnetic Separation's Tailings of Converter Sludge

The absorption effect and absorption behavior of tailings of magnetic separation of converter sludge as test samples on copper ion were investigated.The results show that removal rate of Cu2+ can reach 97.86%, companying with the suitable conditions, that is, the tailings of magnetic separation of converter sludge of 8.0 g/L in dosage, concentration of Cu²⁺ of 20 mg/L and the reaction time 50 min.The importance of adsorption factors are shown as follows：the dosage of tailings > initial concentration of copper ion solution> reaction time.The adsorption reaction mainly consists of the surface  dsorption with somewhat replacement reaction accompanied.
