摘要:
以国外某矿山低品位金矿石为研究对象，开展了高压辊磨和常规颚破产品氰化试验研究，考察2种碎磨工艺对氰化浸金的影响。结果表明：通过高压辊磨，产品中细粒级含量比常规颚破高，可磨性优于常规颚破产品，且有助于降低磨矿成本，同时提高柱浸金浸出率。在相同浸出条件下，高压辊磨产品柱浸金浸出率比常规颚破产品提高了11～15百分点。试验结果可为该金矿及类似矿山进行资源高效开发和综合利用提供参考。

Abstract:
In a case study of the low-grade gold ores from an overseas mine,an experimental study on the cyanidation of high-pressure roller mill and conventional jaw crusher products is carried out and investigates the effect of the 2 comminution and grinding processes on cyanide leaching of gold.The test results show that through the high-pressure roller mill,the fine grain content in the ore products is higher than conventional jaw crusher crushing,and the grindability is better than that of the product from conventional crushing.Besides it helps reduce the cost of grinding and improve the column leaching rate of gold.Under the same leaching conditions,the column leaching rate of high-pressure roller mill products is 11-15 percentage points higher than that of the conventional crushing products.The experimental results can be referred to by the gold mine and similar mines when it comes to high-efficient development and comprehensive utilization of resources.
