摘　　要：针对缅甸某氧化铜矿石特点,确定了硫氧混合浮选的原则工艺流程,在条件试验的基础上进行了小型闭路试验,最终可获得Cu品位23.55%、Ag含量1 919.20 g/t、Cu回收率91.16%、Ag回收率93.08%的铜精矿,银主要富集于铜精矿中,有价元素铜和银得到了很好地回收。Based on the properties of a copper oxide ore from Burma,a bulk flotation process for copper sulfide and copper oxide ores was determined. A small-scaled closed-circuit test was carried out following the condition tests.Finally,a copper concentrate with Cu grade and recovery of 23. 55% and 91. 16%,Ag content and recovery of 1 919.20 g/t and 93. 08%,respectively,was obtained,showing valuable elements,Cu and Ag,were reclaimed effectively.
