| Abstract: | For the property of Nongruri gold mine in Tibet,the flotation process of one roughing,four scavenging and two cleaning separation is adopted,using sodium butyl xanthates and ammonium-butyl aerofloat as collectors,and water glass as disperser,and terpineol as frother under grinding fineness of less than 91.97% -0.074 mm.The gold concentrate grading of 172.83 g/t at a 93% recovery and a 3.00% yield with 0.36 g/t Fe grade in tailing was obtained,providing a reasonable process for development and utilization of the ores. |
