采用“敏杰”提金剂堆浸工业试验研究及应用

Industrial test and application of "Minjie" gold extraction agent in heap leaching

"敏杰"提金剂具有低毒环保、浸出速度快、使用方法简单等优点,在碱性条件下替代NaCN浸金效果较好,可大大降低环境污染压力。张家口弘基矿业有限责任公司采用"敏杰"提金剂进行了金矿堆浸工业试验研究和生产应用,结果表明:在金矿石堆浸生产中,"敏杰"提金剂完全可以替代NaCN进行浸金,其生产技术指标与NaCN浸金相当,金浸出率达到50%以上,具有良好的经济效益、环境效益,可在黄金行业推广应用。

Minjie extraction agent has the advantages like low toxicity,fast leaching and simple operation.It per-forms well in the process of gold leaching replacing NaCN in alkaline conditions and can greatly reduce the pressure of environmental protection.Zhangjiakou Hongji Mining adopted Minjie gold extraction agent to carry out industrial tests on gold heap leaching and production application.The results show that in heap leaching process,Minjie gold extrac-tion agent can replace NaCN;its technical index equals that of NaCN and the gold leaching rate can be over 50 %. Minjie gold extraction agent provides good economic and environmental benefits and is worth promotion in gold indus-try.
