| Abstract: | According to the property of a low grade microgranular disseminated gold ore from Gansu,a contrast ex-periment is carried out among the processes of fine grinding flotation,coarse grinding flotation,and coarse grinding flo-tation-rough concentrate regrinding flotation.The results show that the fine grinding flotation process is the best,man-aging to obtain gold concentrates with gold grade of 21.25 g/t and gold recovery rate of 85.80 %.Practice witnesses a good production index with outstanding economic profits. |
