Abstract: The gold in a gold mine in Shaanxi is mainly composed of micro and super micro natural gold particles,to resonable develop and utilize the gold resources,gravityflotation combined beneficiation was cjonducted according to the ore properties,gravity separation study was using Nielsen concentrator.The final obtained gold grade of gold concentrate 1 is 5 250 g/t,gravity tailings via flotation,gold grade of gold concentrate 2 is 41.17 g/t,total gold recovery is 95.45%,gold grade of tailings is 0.09 g/t.Compared with single process,application of combined process is benifit for obtain better metallurgy index,the resources can be better resonable develop and utilization.
Key words: Lean sulfur gold ore, Fine particle gold, Knelson concentrator, Gravityflotation combined process
