对云南某低铜含钴黄铁矿进行了可选性试验研究。采用铜钴混合浮选、优先浮铜再浮含钴黄铁矿两种流程，结果表明，采用铜钴混合浮选工艺流程，可获得含Cu 0．21％、Co 0．81％、S 52．79％，Co回收率为90．07％的混合精矿，流程简单，成本低；采用优先浮铜、再浮选钴工艺流程获得的铜精矿含Cu 20．15％、Cu回收率49．12％，钴精矿含Co 0．81％、Co回收率91．41％，该流程复杂，但能有效回收铜，略提高钴回收率。
對雲南某低銅含鈷黃鐵礦進行瞭可選性試驗研究。採用銅鈷混閤浮選、優先浮銅再浮含鈷黃鐵礦兩種流程，結果錶明，採用銅鈷混閤浮選工藝流程，可穫得含Cu 0．21％、Co 0．81％、S 52．79％，Co迴收率為90．07％的混閤精礦，流程簡單，成本低；採用優先浮銅、再浮選鈷工藝流程穫得的銅精礦含Cu 20．15％、Cu迴收率49．12％，鈷精礦含Co 0．81％、Co迴收率91．41％，該流程複雜，但能有效迴收銅，略提高鈷迴收率。

The beneficiability of a Co?bearing pyrite with low content of copper was studied with two flowsheets, a Cu?Co bulk flotation and a Cu?preferential flotation prior to the flotation of Co?bearing pyrite. The results show that the simple and economic approach of bulk flotation led to a bulk concentrate containing 0.21% of Cu, 0.81% of Co and 52.79% of S, with a Co recovery of 90. 07%, while another process flowsheet resulted in 49. 12% Cu recovery to a copper concentrate grading 20.15% Cu and 91.41% Co recovery to a cobalt concentrate grading 0.81% Co, respectively. It can be seen that the selective flotation technique, though comparatively complex, is more effective in copper recovery and can also slightly increase the Co recovery rate.
