摘　　要：针对云南某新生代红土型露天金矿金的粒度分布呈粗细极不均匀的特点,采用高离心力场重选工艺进行研究,较好地解决了粗粒金以及微细粒金的回收难题,当原矿金品位1.1g/t,精矿金品位47.23g/t,金回收率达到86.09%,获得了满意的选别指标。According to the fact that the very uneven dissenmination characteristics of size distribution of Au from a certain cenozoic laterite-type gold ore in Yunnan province, a gravity separation process with high centrifugal force field was studied. With this process, the difficult problem of recovery of coarse grained gold and micro-fine grained gold was preferably resolved, and good techno-economic indices were obtained： gold concentrate grade reached 47.23 g/t, and recovery 86.09g/t while the raw ore grade is merely 1.1 g/t.
