Summary: | The invention discloses a dressing-metallurgy combined method for treating ultra-fine copper sulfide ore. The method comprises the following steps: performing ore grinding on crude ore, adding a collecting agent, adding a foaming agent, performing rough sizing, performing a section of blank quick fine sizing operation on the copper rough concentrate obtained through rough sizing so as to obtain high-grade copper concentrate No. 1 and middling No. 1, perform scavenging operation on the rough tailings obtained through rough sizing so as to obtain tailings No. 1 and middling No. 2, merging the middling No. 1 and middling No. 2, performing ultra-fine grinding so as to obtain an ultra-fine ground product, adding a gangue inhibitor in the ultra-fine grinding process, adding the collecting agentand foaming agent to the ultra-fine ground product, performing ultra-fine grinding rough sizing operation, performing blank and fine sizing on the obtained ultra-fine ground rough-sized concentrate soas to obtain low-grade co |
