| Abstract: |
| The mixed flotation of mixed slag (electric furnace slag and converter slag) produced from Chuxiong Dianzhong Non-ferrous Metal Co. LTD was investigated. The mixed slag with a copper content of 1.710 % was ground to -0.050mm (90 %) and then introduced to flotation process. The copper concentrate with a grade of 21 % and tailings with a grade lower than 0.28 % could obtain from the secondary roughing, secondary scavenging and thrice flotation of rough concentrate (without milling) processes. The recovery rate of copper of this process was high up to 85 % and has been heighted after process reforming in productive practice. |
