| Abstract: | In view of the properties of the high oxidation of a certain refractory gold-silver ore and the fine dissemina- ted grain size of gold and silver in Hubei, it ultimately determined to adopt the process of all-sliming cyanidation to recover gold and silver in ore by the contrast tests of flotation, gravity separation and leaching. The beneficiation indi- cator was obtained：the leaching rates of gold and silver were 68.32% and 64. 13% respectively. This process provid- ed the technical direction for the reasonable development of this type of gold-silver ore, at the same time, put forward the effective recovery approach of high oxidation-type gold-silver ore. |
