A flotation method for improving beneficiation index of gold-bearing copper sulfide ore |
| abstract |
The invention discloses a flotation method for improving the beneficiation index of gold-bearing copper sulfide ore, and belongs to the technical field of metallurgical beneficiation. Based on the technical route of "thiosulfate dissolution - sulfide precipitation - hydrogen peroxide + starch coupling inhibition - copper and sulfur selective flotation separation", the separation of gold-bearing copper sulfide ore is carried out. The steps of the flotation method include: (1) rough selection; (2) sweep selection I; (3) selection I; (4) sweep selection II; (5) selection II; (6) selection III. Through the flotation method of the present invention, the gold in the carrier minerals can be converted into independent gold sulfide minerals, the loss of the gold contained in the pyrite to the tailings can be avoided, the synergistic benefit of the combined inhibitor can be fully exerted, and the gold, The quality and recovery rate of copper concentrate can realize the economical, efficient and clean development and utilization of gold-bearing copper-sulfur ore under low alkalinity. |
