金精礦氰化尾渣鉛和銅的回收

Recovery of lead and copper from cyanide tailings

  • 摘要: 采用優先浮選鉛、再活化浮選銅的工藝流程對某金精礦氰化尾渣鉛、銅回收進行研究.閉路實驗表明:石灰作抑制劑,乙硫氮(二乙基二硫代氨基甲酸鈉)和丁基黃藥(丁基黃原酸鈉)作捕收劑,通過"一粗兩掃兩精"流程,得到回收率為90.48%、品位為45.24%的合格鉛精礦;以NP(銅、鋅無機鹽組合藥劑)作銅活化劑,有機抑制劑FM抑制黃鐵礦,Z-200(O-異丙基-N-乙基硫逐氨基甲酸酯)和丁銨黑藥(二丁基二硫代磷酸銨)作捕收劑,采用"一粗兩掃兩精"流程,得到回收率為82.17%、品位為19.28%的合格銅精礦;金、銀同時富集于鉛精礦和銅精礦.

     

    Abstract: The flowsheet of the selective flotation of lead and the activation flotation of copper was adopted to recover lead and copper from cyanide tailings. Closed circuit test results show that the qualified lead concentrate with the recovery of 90.48% and the grade of 45.24% can be produced with lime as a stabilizer, sodium diethyl dithiocarbamate (N, N-diethyldithiocarbamate) and butylxanthate (butyl sodium xanthate) as combined collectors, and by using the flotation flowsheet of one roughing, two scavengings and two cleanings. The qualified copper concentrate with the recovery of 82.17% and the grade of 19.28% can be produced with NP (a combined reagent by inorganic copper salts and inorganic zinc salts) as an activator, organic depressant FM as a stabilizer, Z-200 (O-isopropyl-N-ethyhhioearbamate) and butyl ammonium aerofloat (ammonium dibutyl dithiophosphate) as combined collectors, and by using the flotation flowsheet of one roughing, two scavengings and two cleanings. Gold and silver are also simultaneously enriched within the two kinds of concentrates.
