真空缓冷铸渣机冷却炉渣选铜的研究
STUDY ON COPPER SEPARATION FROM SLOWLY COOLED SLAG OF A VACUUM SLAG CASTING MACHINE
【摘要】 介绍了真空缓冷炉渣的工艺矿物学特性 .试验研究结果表明 ,该炉渣属于中等可碎性偏难 ,硬度系数在 8~ 16之间 .在磨矿细度为 - 0 .0 16mm占 89%时 ,粗、扫选抛尾 ,粗精矿再磨再选 ,以 Z- 2 0 0 ,SN- 9和丁胺为混合捕收剂 ,最终得到铜精矿产率为 4 .59% ,精矿含铜 2 3.4 8% ,含金5.8g/ t,铜回收率为 83.70 % ;尾矿含铜 0 .2 2 % ,含金 0 .18g/ t.
【Abstract】 The technological mineralogical characteristics of slowly cooled slag under vacuum are introduced.The test results indicate that the slag belongs to the medium re- ductibility,on the difficult side,and its coefficient of hardness is from 8to 1 6 .When the slag with grinding fineness of- 0 .0 1 6 mm amount to89% ,rough flotation and scavenging are conducted to throw away tailings,then the rougher concentrate is regrounded and re- treated,with Z- 2 0 0 ,SN- 9and ammonium dibutyl dithiophosphate as a mixed collector,the productivity of the final copper concentrate is4.5 9% .It contains Cu2 3.48% and Au5 .8g/ t.The recovery of Cu is 83.70 % .The tailing contains Cu 0 .2 2 % and Au 0 .1 8g/t.
