摘要
采用浮-重联合选别工艺,处理含铜2.88%、铅1.02%、锌0.29%、硫3.60%、银49g/t的铜铅多金属硫化矿。铅精矿产率为0.43%,品位61.12%,银品位726.88g/t,互含铜品位3.83%。铜精矿的产率为12.79%,品位21.05%,银品位286.30g/t,互含铅4.59%,铜的回收率可达93.40%,银的总回收率为81.11%。相对于全浮选流程,浮-重联合流程具有工艺简单、投资低、设备少、生产成本低、环保、处理能力大等优点。应用于实际生产,各项指标稳定,效益明显。
The multi-metal sulfide ore with the contents of Cu 2.88 %, Pb 1.02 %, Zn 0.29 %, S 3.60 %, Ag 49 g/t is beneficiated by combined technology of flotation-gravity separation. The yield, grades of lead, silver and copper for the lead concentrate are 0.43 %, 61.12 %, 726.88g/t and 3.83 %, respectively. The yield, grades of copper, silver and lead for the copper concentrate are 12.79%, 21.05%, 286.30g/t and 4.59%, respectively. The copper recovery is up to 93.40%, and the total recovery of silver is 81.11%. Comparing to the full floatation flowsheet, the combination of flotation-gravity separation has some advantages, such as simplified flowsheet, low investment cost, less equipments, low operation cost, environmental friendship, large capacity in production. Stable indexes and remarkable benefit are achieved in the practical application of the combination technology.
