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
