| 摘 要： | 山东某含金硫铁矿原矿金品位为3.06 g/t、含硫量为2.65%。工艺矿物学研究表明，金主要以自然金等独立金矿物形式存在，其次以黄铁矿为载体，少量以磁黄铁矿为载体。采用快速浮选和常规浮选组合的工艺流程，以硫酸铜做活化剂，MA-1做捕收剂，HX-609做起泡剂，分别获得了金品位为34 g/t、32 g/t的快速浮选精矿和常规浮选精矿，金总回收率达到90%以上。

| Abstract: | The gold grade of a gold-bearing pyrite ore in Shandong is 3.06 g/t, and the sulfur content is 2.65%. Process mineralogy research showed that gold mainly existed in the form of natural and other independent gold minerals with pyrite as the primary carrier and pyrrhotite as the secondary carrier. The combination process of rapid flotation and routine floatation was adopted, with copper sulfate as the activator, MA-1 as the collector, and HX-609 as the foaming agent. The gold grade of the obtained rapid flotation concentrate and routine flotation concentrate were 34 g/t and 32 g/t, respectively, and the total recovery rate of gold reached more than 90%. |
