分选钼矿石的困难是由矿石物质成分的一些特点造成的。其中主要有: 1.要使硫化物连晶及硫化矿物与脉石矿物连生体更完全的解高,必须把某些选矿产品磨得很细。此外,在拟定磨矿制度和选矿流程时,首先必须考虑到,较软的辉钼矿颗粒在磨矿时会被脉石和黄铁矿坚硬颗粒的锐利棱角所切削,从而可以造成辉钼矿过磨、回收率降低和精矿质最变坏。其次,辉钼矿和脉石颗粒在磨机中互磨时,后者也得到了浮游活性,致使精选作业效率降低,精矿质量变坏。
The difficulty of sorting molybdenum ore is caused by some characteristics of the ore material composition. Some of them are: 1. In order to make the sulfide crystals and sulfide minerals and gangue minerals even more completely elevated, you must wear some very fine mineral products. In addition, in developing the grinding system and beneficiation process, it must first be considered that softer molybdenite particles can be cut by the sharp edges of gangue and pyrite hard particles during grinding, which can lead to molybdenite over Mill, lower recovery rate and concentrate quality is the worst. Second, when molybdenite and gangue pellets are ground into each other in the mill, the latter also has the property of floating, resulting in reduced efficiency of selective work and deterioration of concentrate quality.
