峰背比法判断X射线辐射分选机预选低品位钼矿的最佳工艺条件

摘要

The value of IP/IB is adopted to determine the optimal process conditions pro-sorting low grade molybdenum ore by X-ray radiation separator. The results indicates that when aimed molybdenum ore containing several size class, the optimal excited voltage of X-ray tube and the measurement distance are 45 kV and 4 cm respectively.%以峰背比法定性判断X射线辐射分选机分选低品位钼矿石的最佳工艺条件.试验研究表明,X射线辐射分选机在分选含有不同粒级的低品位钼矿原矿时,X射线管最佳激发电压应该选择45 kV,而测量距离在4 cm左右时,可获得最佳测量结果.
