摘要/Abstract

摘要： 滇西某低品位含金银铜铅锌多金属硫化矿原矿铜、铅、锌、硫含量分别为0. 42%、0. 58%、0. 60%、
11. 18%,伴生Au、Ag 品位分别为1. 73、34. 66 g/ t,矿石中主要金属矿物为黄铜矿、黄铁矿、方铅矿及铁闪锌矿,各金属
硫化矿物赋存状态复杂、嵌布粒度偏细。伴生金、银分别以含银自然金及辉银矿为主,嵌布粒度微细,与主要金属矿物
赋存关系极为复杂,该矿石属铁闪锌矿型复杂难选低品位铜铅锌多金属硫化矿,综合回收难度较大。为高效综合开
发利用该矿石资源,进行了全面的铜-铅-锌-硫全优先浮选工艺流程试验研究。在磨矿细度-0. 074 mm 占90%的条
件下,全优先浮选闭路试验可获得铜精矿Cu 品位27. 25%、Cu 回收率82. 40%,铅精矿Pb 品位47. 33%、Pb 回收率
79. 16%,锌精矿Zn 品位45. 79%、Zn 回收率79. 37%,硫精矿S 品位48. 88%、S 回收率83. 20%,主要有价元素铜、铅、
锌、硫均得到高效回收,各金属矿物分离较为彻底,精矿杂质互含低,伴生元素金、银总回收率分别为85. 71%、
85. 18%,回收指标较为优良,可为该资源的开发与利用提供技术支撑。

Abstract: The raw ore of a low-grade polymetallic sulfide ore containing gold,silver,copper,lead and zinc,located in
western Yunnan,containing copper of 0. 42%,lead of 0. 58%,zinc of 0. 60%,and sulfur of 11. 18%. The associated gold (Au)
and silver (Ag) contents are 1. 73 g/ t and 34. 66 g/ t,respectively. The main metallic minerals present in the ore are chalcopyrite,
pyrite,galena,and marmatite. The occurrence states of these sulfide minerals are complex,with relatively fine particle sizes.
Associated gold mainly occurs as silver-bearing native gold,while silver is predominantly hosted in pyrite,both exhibiting
fine-grained dissemination. The existence relationships among the major metallic minerals are highly intricate. This ore can be
classified as a complex iron sphalerite-type polymetallic sulfide ore with low grade,posing significant challenges for mineral
processing. To achieve efficient and comprehensive utilization of this ore resource,a systematic experimental study was conducted
on the sequential flotation process for the recovery of copper,lead,zinc and sulfur. The experimental results demonstrated
the successful production of copper concentrate with a Cu grade of 27. 25% and a recovery rate of 82. 40%,lead concentrate
with a Pb grade of 47. 33% and a recovery rate of 79. 16%,zinc concentrate with a Zn grade of 45. 79% and a recovery rate of
79. 37%,and sulfur concentrate with an S grade of 48. 88% and a recovery rate of 83. 20%. The principal valuable elements
(copper,lead,zinc,and sulfur) were effectively recovered,and the separation of different metal minerals was relatively complete,
resulting in low impurity levels in the concentrates. Furthermore,the total recovery rates for the associated elements gold
and silver reached 85. 71% and 85. 18%. The recovery indicators are highly favorable,providing robust technical support for
the development and utilization of this resource.
