| Abstract: |
| High content in each other of concentrate and metals loss to Multi-metal sulfide ore in Gansu due to ore property changing.In order to solve this problem,new modifier T11and TC on flotation experiments were carried out.The selection index can be obtained by the closed circuit test:a Cu concentrate contenting Cu 22.78% with recovery is 80.60% ,contenting Pb+Zn 14.30%; Pb-Zn concentrate contenting Pb+Zn 39.23% with recovery is 175.16%.Under proper Cu recovery and Pb+Zn recovery,Cu concentrate grade increased by 1.01% and the content of Pb+Zn reduced by 2.04%, Pb-Zn concentrate grade increased by 1.01%,compared with the on-site production. |
