我国钼矿资源丰富,储量名列世界前茅,具有潜在的战略优势。在我国钼选厂陆续兴建,老选厂需要改造的形势下,研究辉钼矿的选矿工艺流程,总结我国卅五年的实践经验是必要的。不同钼矿床的辉钼矿有其个性和共性。本文就单一辉钼矿的共性,结合试验研究和生产实践,分析选钼工艺流程。一、辉钼矿选矿的两个共性 (一)辉钼矿的可浮性众所周知,辉铝矿为天然疏水矿物之一,其天然疏水性主要由其结晶构造和键的性质决定。在辉钼矿的结晶构造层内,由化学键系结坚密;在构造层间,由残余键(范德华氏键)结合松弛。辉钼矿受外力后,残余键断裂,解离为强疏 China is rich in molybdenum resources, reserves rank among the best in the world, with potential strategic advantages. In our country Molybdenum election plant one after another to build, the old election plant needs to be transformed situation, research molybdenum beneficiation process, summed up China’s five years of practical experience is necessary. Molybdenum ore molybdenum mine has its own personality and commonalities. In this paper, a common molybdenum mine common, combined with experimental research and production practices, analysis of selected molybdenum process. First, the two common molybdenite beneficiation (A) flotability of molybdenite It is well known that gibbsite is one of the natural hydrophobic minerals, its natural hydrophobicity is mainly determined by the crystal structure and the nature of the bond. In the molybdenite crystal structure layer, the bond by the chemical bond strong; in the structural layer, by the residual bond (Van der Waals bond) relaxation. Molybdenite affected by external forces, the residual bond fracture, dissociation to a strong sparse
