为了保护水资源环境，实现绿色发展和环保提金，试验研究通过小试对10种新型环保提金剂进行浸出，从中选择效果较好的环保提金剂进行工业试验。工业试验结果表明：该提金剂具有环保、浸出速度快及使用方法简便的优点，吨矿耗量为747 g/t，金浸出率达70.47%，尤其对氧化矿浸出效果更好，浸出率可达75.16%。某提金剂应用于炭浆提金生产中，6个月生产实践结果表明：某提金剂完全可以替代NaCN，吨矿耗量为650 g/t，金浸出率达到72.92%，单位成本可降低4.78 元/t，生产成本可节省57万元/年，具有良好的经济效益且环境效益显著，可在黄金行业推广应用。

In order to protect water resources，realize green development and gold extraction with environmental protection，it was tried to use ten pro-environment type regents for gold leaching，and selected better regents used for further industrial test.The results showed that one of the gold extraction regents had the advantages of environmental protection，fast procedure and easy operation.For example，leaching efficiency reached to70.47% for 747 g/t mineral aggregate，particularly for oxidized ore，leaching efficiency can even be up to75.16%.Thus，the pro-environment type regent was applied to CIP process for six months production.The results of practice in production demonstrated that this gold extraction regent can replace to NaCN，and leaching efficiency was about 72.92%for 650 g/t mineral aggregate，showing that the production cost reduced by 4.78 RMB/t and 0.57 million RMB/year.Obviously，this kind of gold extraction regent has the good economic benefit and remarkable environmental benefit，hence it can be applied in the gold industry in future.
