| Abstract: | According to the properties of the gold ore and its carrier mineral, detailed dressing experiments are carried out, and the optimum process parameters are obtained. Then, the technological process is determined as ＂ one roug- hing-two cleaning--two scavenging, middlings returning in order＂. Finally, with this flowsheet, good test indexes are achieved by a closed circuit flotation test. The results indicate that a gold concentrate with yield of 2. 89%, grade of 85.16 g/t, and recovery of 82. 17% can be obtained under the condition of grinding fineness of -0. 074 mm 70%. |
