铅盐在高铜金精矿氰化提金试验中的应用与工业实践

Experiment and industrial practice of applying lead salts in gold concentrate with high copper cyanide leaching

河台金矿原矿含0 2%～0 3%的铜,以原生硫化铜为主,含硫1%左右,属贫硫化物含铜金矿石。从1989年建厂至1998年一直采用单一混合浮选工艺,生产含铜3%～5%的混合金精矿,这样影响了企业的经济效益。经试验研究采用铅盐预处理工艺获得成功,并建成氰化冶炼厂,本文介绍铅盐在高铜金精矿氰化浸金应用中的试验与工业实践情况。

Crude ore of Hetai Gold Mine contains 02%～03% copper, bases on primary copper sulfide with 1% sulfur, it's lean sulfide gold ore with copper. Single bulk flotation technology had been used from 1989 to 1998, and produced gold bulk concentrate that contained 3%～5% copper, which affected enterprise economic benefit. After experiment and researching, lead slats pretreatment technology was used successfully, and the cyanide refinery was founded. This article mainly introduced the experiment and industrial practice situation of applying lead salts in gold concentrate with high copper cyanide leaching.
