摘要: 内蒙古某银锡多金属矿生产的摇床中矿含有多种有价元素,矿物组成复杂。试样中银品位为9. 8 g/ t、
铜品位为0. 06%、锌品位为0. 41%、硫品位为1. 41%,其中75. 60%的银赋存于银铜矿物中。针对该矿石性质,采用
“银铜硫等可浮—银铜与硫分离—锌硫混浮—锌硫分离”的工艺流程进行选矿试验。以碳酸钠+硫酸锌为锌抑制剂,
石灰为硫抑制剂,丁铵黑药+SAC 为银铜捕收剂,乙基黄药为锌硫分离捕收剂。全流程试验可获得如下指标:银铜精
矿中银品位为3 287. 9 g/ t、回收率为70. 61%,铜品位为16. 34%、回收率为60. 40%;锌精矿中锌品位为41. 09%、回收
率为60. 99%;硫精矿中硫品位为38. 84%、回收率为65. 30%。该工艺实现了摇床中矿中有价元素的高效回收。

Abstract: The shaker middlings produced from a silver-tin polymetallic mine in Inner Mongolia contain multiple valuable
elements and have a complex mineral composition. The sample assays 9. 8 g/ t Ag,0. 06% Cu,0. 41% Zn,and 1. 41% S,among
which 75. 60% of the silver is hosted in silver-copper minerals. Based on the ore characteristics,a flotation flowsheet of “isoflotation
of Ag-Cu-S,separation of Ag-Cu from S,bulk flotation of Zn-S and separation of Zn from S” was adopted for the beneficiation
tests. Sodium carbonate + zinc sulfate was used as the zinc depressant,lime as the sulfur depressant,ammonium dibutyl
dithiophosphate (ADDP) + SAC as the collector for silver-copper minerals,and ethyl xanthate as the collector for the Zn-S
separation stage. The full-flowsheet test yielded the following results:a silver-copper concentrate with an Ag grade of 3 287. 9
g/ t and Ag recovery of 70. 61%,and a Cu grade of 16. 34% and Cu recovery of 60. 40%;A zinc concentrate with a Zn grade of
41. 09% and Zn recovery of 60. 99%;And a sulfur concentrate with an S grade of 38. 84% and S recovery of 65. 30%. This
flowsheet achieves efficient recovery of valuable elements from the shaker middlings.
