摘要: 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。

关键词: 搅拌磨, 难处理金属矿, 细磨

Abstract: 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.

Key words: Stirred mill, Refractory metal ore, Fine grinding
