矿物单体解离是矿物有效分选的先决条件,磨矿是矿物解离的关键工序。磨矿效果的好坏直接影响分选指标,磨矿产品粒度特性是确定磨矿分级设备、浮选工艺流程及药剂的依据。根据磨矿产品粒度特性与浮选的关系,确定最佳的磨矿条件,优化磨矿分级工艺,降低能耗,提高磨矿机生产能力,为有效浮选打下良好基础。本实验主要通过改变磨矿条件(包括磨矿时间、钢球配比,磨矿质量分数)得到磨矿产品,对磨矿产品进行筛分和浮选试验,然后根据浮选结果对磨矿条件进行回归分析,建立数学模型,确定最佳磨矿条件以及在该条件下的最佳粒度分布特性。

Mineral monomer disintegrate is the precondition of the mineral effective separation, grinding is the key process of mineral monomer disintegrate. The quality of grinding directly impacts on the lfotation index, the features of grinding product and the useful components’ particle size distribution characteristics is the base of conifrming ore-milling classiifcation technology and equipment, the lfotation process and agentia. According to the connection between grinding product particle size distribution and lfotation, determining the most appropriate grinding conditions, optimizing the grinding classiifcation process, reducing the energy consumption and improving the production capacity of grinding machine. This paper mainly through changing grinding conditions (including grinding time, steel ball ratio, and grinding concentration) to get the grinding product ,and then having screening and lfotation tests. Regression analysis of grinding conditions is adopted based on lfotation results. Finally, grinding conditions are selected, the best particle size distribution is conifrmed.
