摘要
辽宁某铜铅锌多金属硫化矿石中的有用矿物嵌布关系复杂,嵌布粒度粗细不均。采用1次磨矿、电位调控优先浮选工艺对铜、铅、锌的选矿工艺条件进行了试验研究。结果表明,在电位约-35mV、pH=9.1情况下,以SN-9#+苯胺黑药为捕收剂、Na2SiO3+ZnSO4+CMC为铅锌及脉石矿物的抑制剂优先选铜,接着在电位为-225.6mV、pH=11.4情况下,仍以SN-9#+苯胺黑药为捕收剂浮选铅,最后以硫酸铜为活化剂、乙基黄药为捕收剂选锌,最终获得了铜品位为23.68%、回收率为85.61的铜精矿,铅品位为51.26%、回收率为70.68%的铅精矿,锌品位为52.13%、回收率为82.13%的锌精矿。
The valuable minerals of copper-lead-zinc poly-metallic sulfide ore have complex dissemination with uneven grain size. Beneficiation experiment on copper,lead,zinc by using one grinding and potential controlled preferential flotation was conducted. Results indicated that using SN-9#＋ aniline aerofloat as collector,Na2SiO3＋ZnSO4＋CMC as inhibitor at potential of-35 mV,pH = 9. 1 for copper preferential flotation,then using SN- 9#＋ aniline aerofloat as collector at potential of-225. 6 mV,pH = 11. 4 for lead flotation,finally using copper sulfate as activating agent,ethyl xanthate as collector in zinc flotation,copper concentrate with copper grade of 23. 68% and recovery of 85. 61%,lead concentrate with lead grade of 51. 26%and recovery of 70. 68%,and zinc concentrate with zinc grade of 52. 13% and recovery of 82. 13% was obtained respectively.
