摘要: 为有效回收大厂锡石-多金属硫化矿尾矿中的有价元素,对该尾矿进行了预选抛尾试验研究。试验结果表明,预选抛尾对该尾矿是行之有效的,可抛弃产率为44.66%的尾矿,不仅提高了入选品位,还降低了选矿成本。通过对比原矿直接浮选铅锑和预选粗精矿浮选铅锑的试验,预选抛尾具有较理想的选别指标。

Abstract: To effectively recover the valuable elements from the tailings of Dachang cassiterite multi-metal sulfide ore, pre-concentration for Tailing Discarding was tested on the tailing. The result shows that preconcentration for tailing discarding is effective for this tailing. It can discard tailing that has a yield of 44.66%, which can not only improve the feed grade but also reduce the concentration cost. The comparative tests with the processes of direct flotation of lead and antimony from the raw material and the flotation of rougher concentrate to separate lead and antimony show that tailing pre-discarding can achieve ideal metallurgical performance.

Key words: Cassiterite multi-metal sulfide ore, Preconcentration for tailing discarding, Lead and antimony
