摘要
本文对氨氰法浸取含铜金矿石进行了工艺过程研究，详细地考查了各操作条件对金浸取率的影响。对于含４．６７％Ｃｕ及５８ｇ／ｔＡｕ的金精矿，氨氰法的ＮａＣＮ用量约为氰化法的１／３，并且金浸出率也高，可达９３．５％。将实验结果用于工业生产厂（２８ｔ／ｄ）时，运转稳定正常，技术指标与小试结果相符合。
The experimental research of gold leaching of copper-bering gold ore by ammoniacalcyanide process and the effecta of various operation condition on gold extraction have been investigstedin this paper.For gold concentrates containing 4.76%Cu and 58g/t Au,the NaCN consumption in ammonincal cyanide process only corresponds to 1/3 of that in conventional cyanide process and the goldleaching ratio has been improved to 93.5%.Applying the experimental results to industrial plant(28t/d),the operation is stable and the technical targets are consistent with the results of the smallscale experiment.
