某钨锡矿选厂钨锡尾矿中含锌1．13％，锌矿物主要是闪锌矿，属二次资源，具有再回收价值。在查明锌矿物赋存状态和分析研究的基础上，对该尾矿进行浮选回收锌的选矿试验研究。通过一粗三精二扫，获得含锌52．02％，锌回收率84．42％的锌精矿。有效回收了尾矿中的闪锌矿，为企业创造了经济效益。
某鎢錫礦選廠鎢錫尾礦中含鋅1．13％，鋅礦物主要是閃鋅礦，屬二次資源，具有再迴收價值。在查明鋅礦物賦存狀態和分析研究的基礎上，對該尾礦進行浮選迴收鋅的選礦試驗研究。通過一粗三精二掃，穫得含鋅52．02％，鋅迴收率84．42％的鋅精礦。有效迴收瞭尾礦中的閃鋅礦，為企業創造瞭經濟效益。

The Zn content of a tungsten - tin tailings is 1 .13% , the main zinc mineral is sphalerite . These minerals belong to secondary resources ,and has recovery value .Based on the analysis and study on the oc‐currence states of znic minerals ,flotation was used in this test to recover znic from the tailings .Zn concen‐trate with Zn grade of 51 .82% and zinc recovery of 84 .37% was obtained by adopting the process of one roughing ,three -cleaning ,two -scavenging .It effectively recovered sphalerite in the tailings and brought economic benefits for the enterprise .
