异丁基黄药对黄铜尾矿有价元素铜的浮选技术研究

The Technology Reseaech of Flotation on Copper Tailing by Isobutyl yellow

随着经济、科技的不断发展,全世界对铜的需求量也不断增加,铜矿开采加剧造成尾矿堆积使环境污染加剧、资源浪费日益严重,铜矿资源开展二次利用就很有意义。选择"磨矿—浮选"的工艺流程进行浮选,再利用控制变量的方法,通过实验确定对铜尾矿最佳的浮选条件,实验结果包括最佳工艺条件,包括测定磨矿细度95%,捕收剂异丁基黄药的用量150 g/t,起泡剂二号油的用量40 g/t,抑制剂氧化钙用量1.5 g/Kg,分散剂碳酸钠的用3.0 g/Kg。最红可获得铜品位为2.10%、回收率为59.98%的铜精矿。

With the continuous development of economy, science and technology, the world is also increasing demand for copper, copper mining aggravate tailings stacking exacerbated the environmental pollution and resource waste is becoming more and more serious. Chooses the process flow of “grinding and flotation” according to the mineral characteristics.Us the method of control variables, the flotation of copper tailings best conditions were determined through the experiment, including the determination of 95% grinding fineness, the collectordosage of isobutyl xanthate is150 g/t, the dosage of the no.2 oil is 40 g/t, the dosage inhibitor calcium is 1.5 g/Kg, the dosage of dispersant sodium is 3.0 g/Kg. Eventually concentrate was recovery 59.98% in series tests.
