| Abstract: | 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. |

| Keywords: | cenozoic laterite-type gold ore size of gold high gravity separation process with high centrifugal force field |
