| Abstract: |
| In this paper, the flotation test of a tiny refractory gold ore containing arsenic and carbon is investigated. After the feed ore was milled to a grinding fineness of -0.074mm 80%,a closed-circuit flow sheet consisting of two stages of roughing,three stages of cleaning and three stages of scavenging was adopted in the experimental study under the optimum flotation reagent conditions, obtains a gold concentrate grading 41.90% at 80.64% recovery. Research results of mineralogy show that gold in tailings mainly exists in the form of fine and poor conjoined sulfide and encapsulating sulfide which is difficult to recover effectively by flotation process. |
