搅拌磨在难处理金属矿细磨中的应用

微细嵌布难选矿石在我国分布广，涉及铁、铜、钼、铅锌、黄金等金属矿种，搅拌磨技术是实现微细嵌布难选矿石细磨的关键技术。介绍搅拌磨在难处理钼矿、铁矿、金矿中的典型应用实例。这些实例表明，搅拌磨可在提高目标矿物单体解离度的同时，使细磨产品具有窄的粒度分布，减少目标矿物泥化，从而实现精矿品位和回收率的共同提高，并且可显著提高能量利用效率。

The Application of Stirred Mill in Fine-grinding of Refractory Metal Minerals

Fine-disseminated refractory minerals are abundant in china，including many metal minerals such as Fe，Cu，Mo，Pb-Zn，Au etc.Stirred mill is the key technology to acquire high-grinding products of fine liberated refractory ores.Several application cases for fine-grinding of Mo，Fe，Au ores by stirred mill were illustrated in this paper.The results indicated that the stirred mill improved the liberation level of single mineral，and made the grain distribution in a narrow range and reduce the sliming of the target minerals.Then，the grade and recovery of concentrate can be improved and the energy efficiency is greatly increased.
