摘　　要：为优化选矿工艺流程和技术指标,提高产品质量,对某选矿厂改造后的生产流程进行技术考察,对细破及细筛分技术的考察结果进行分析总结,并提出一系列具体的优化措施。实践证明,改进措施效果良好,尾矿品位降低,收率提高。In order to optimize the technics process and technical indicators of mine choosing and improve the products＇ quality, the production process of one improved mine choosing plant is being examined technically. Analyzes and summarizes the examination results of improved fine crushing and screening technology. Proposes a series of specific optimize measures. The application shows that the improved measures have good effect. The grade of tailing coal mines is reduced and the recovepy rates are improved.
