高压辊磨对矿石中金浸出影响试验研究

介绍高压辊磨机的工作原理及其在黄金矿山的应用情况，对高压辊磨和常规破碎样品进行粒度筛析试验。结果表明，高压辊磨后细粒部分比例大幅提高，高压辊磨技术的应用可达到多破少磨的效果；对高压辊磨和常规破碎后样品进行了对比氰化试验，结果表明，如果采用全泥氰化工艺，则高压辊磨与常规破碎在金浸出率上没有明显优势；如果采用堆浸工艺，则经高压辊磨后，金浸出率比常规破碎样品有较大幅度的提高，3种样品金浸出率分别从65.15%、52.74%和76.05%提高至77.27%、85.71%和87.46%。

Experimental Study on the Effect of Leaching of Gold Ore by High Pressure Roller Mill

We introduce the working principle and the application of the high pressure roller millin gold mine.Granularity sieve analysis test of which the high-pressure roller mill samples and the conventional crushing samples show that the proportion of fine part was substantial increased by high pressure roller mill.So the application of high pressure roller grinding could achieve the effect of more crushing and less grinding.And the cyanide test showed that：compared with the conventional crushing，the high pressure roller mill has obvious advantages in heap leaching process，and the gold leaching rate of three samples were improved greatly，which were increased from 65.15%，52.74%，76.05% to 77.27%，85.71%，87.46%.But it has not difference in all-slime cyanidation process for the gold leaching rate between high pressure roller mill and conventional crushing.
