摘    要:对某高砷含碳低品位难选金矿进行了浮选试验研究。采用碳酸钠和水玻璃为调整剂, 实现了矿泥分散和脉石矿物的选择性抑制; 采用Y89-0为捕收剂, 实现了对载金矿物(黄铁矿和砷黄铁矿)的选择性捕收。在磨矿细度-0.074 mm粒级占80%条件下, 采用一粗二精三扫闭路浮选流程, 在原矿金品位2.36 g/t时, 可获得精矿金品位36.08 g/t、回收率86.77%的良好指标。

关 键 词:金矿  黄铁矿  砷黄铁矿  黄金  浮选

Abstract:Flotation testing of a high-arsenic lean refractory carbonaceous gold ore was performed with sodium carbonate and water glass as regulators, showing slime well-dispersed and gangue minerals selectively depressed. The selective collection of gold-bearing minerals (pyrite and arsenopyrite) was actualized by using Y89-0 as the collector. After the feed ore with the gold content of 2.36 g/t was milled to a grinding fineness of -0.074 mm 80%, a closed-circuit flowsheet consisting of one stage of roughing, two stages of cleaning and three stages of scavenging was adopted in the experimental study, producing a gold concentrate grading 36.08 g/t Au at 86.77% recovery.
Keywords:gold ore  pyrite  arsenopyrite  gold  flotation
