某铜矿床自然铜类型和赤铜矿类型氧化铜矿石,采用筛选——浮选联合流程选收矿石中的自然铜和氧化铜获得成功。矿石细磨后筛选,是处理粗粒片状自然铜的有效选收方法。氧化铜硫化后浮选,其效果也令人满意。一、矿石特征该矿床自然铜类型矿石中的主要含铜矿物是自然铜,赤铜矿居次,此外尚有少量的孔雀石。赤铜矿类型矿石中,自然铜和赤铜矿的含量非常接近,其中也含有少量的孔雀石。自然铜和赤铜矿矿石物相分析结果见表1。
A copper deposit of natural copper type and red copper oxide type copper oxide ore, the use of screening - flotation combined process of natural ore and copper oxide ore received success. Fine grinding ore after screening, is the treatment of coarse-grained flake natural copper effective selection method. Copper sulfide after flotation, the effect is satisfactory. First, the ore characteristics The natural copper-type ore deposits of the main copper-bearing minerals are natural copper, secondary to red copper, in addition to a small amount of malachite. Red copper type ore, natural copper and red copper ore content is very close, which also contains a small amount of malachite. Natural copper and red copper ore phase analysis results in Table 1.
