磨矿是选别前极其重要的准备作业、磨矿作业单元工作的优劣(处理量大小,磨矿产物粒度组成,磨矿用水和能耗)在很大程度上决定着选矿厂技术经济指标的高低。在选钼厂通常采用粗磨粗选粗精矿再磨再选“工艺流程”。粗选作业、原矿磨矿产物的特性必须适于粗选要求,在精选作业,为了获得含钼54%的优质钼精矿,粗精矿再磨应使辉钼矿充分单体解离,单体解离度要高达90—95%,最后一段再磨的磨矿细度要达到—400目95%到—500目95%. Grinding is an extremely important preparatory operation before sorting, the pros and cons of the grinding unit work (size of the treatment, particle size of grinding products, grinding water and energy consumption) to a large extent determines the technological economy of the concentrator The level of indicators. Molybdenum plant in the election are usually rough coarse rougher concentrate grinding and then re-election “process.” Roughing operations, the characteristics of ore grinding products must be suitable for roughing requirements, in the selection of operations, in order to obtain 54% molybdenum molybdenum concentrate of high quality, coarse concentrate grinding should make molybdenite sufficient monomer dissociation, Monomer dissociation as high as 90-95%, the last paragraph of grinding grinding fineness to reach -400 95% to 95% to 95 mesh 95%.
