摘要
In Hebei province there is a single Mo porphyry deposit in which molybdenite is the major metal mineral.In order to improve the grade of the concentrate and the recovery a test of combination of mixed collector of kerosene+ oil No.2(2∶1)and a new collector PE-100 is carried out and recovery of the concentrate is improved by 2% and the grade is slightly improved.For cost reduction stage milling of ore is adopted,i.e.the raw ore is milled to mesh-200 about 60% when a roughing and scavenging is carried out.Then the rough concentrate is milled to mesh-400 about 85% and 5 times of careful concentration conducted with final Mo concentrate of w(Mo)=50.007% and recovery of 89.90%.
