众所周知,硫化铜矿石浮选通常都需要用捕收剂,如黄药等。然而,不用任何捕收剂的硫化铜矿石浮选已由中南工业大学首先研究成功。无论对斑岩铜矿还是矽卡岩铜矿、浸染状铜矿,也无论是高品位铜矿石还是低品位铜矿石,都能实现无捕收剂浮选并获得与加捕收剂浮选相同的指标(见下表)。其中含Cu1.88%的浸染状铜矿石,一次粗选一次精选小型闭路试验,获得了铜品位26.15%,回收率95.3%的铜精矿。现正在准备进行工业试验。无捕收剂浮选不仅在实践中可以不用捕收剂,减轻污染公害,而且在理论上还涉及到硫化矿物天然可浮性 As we all know, copper sulfide flotation usually need to use collectors, such as xanthate. However, copper sulphide ore flotation without any collector has been successfully studied by Central South University of Technology. Whether for porphyry or skarn copper, dip-like copper, and whether high-grade copper ore or low-grade copper ore, can achieve collector-free flotation and get collector and collector float Select the same indicator (see the table below). Which contains Cu1.88% of disseminated copper ore, a rough selection of a small closed-circuit test, access to copper grade 26.15%, 95.3% recovery of copper concentrate. Industrial testing is now under preparation. No collector flotation not only in practice can not collectors to reduce pollution hazards, but also in theory also involves the natural floatability of sulfide minerals
