Constraint of Mineralogical Characteristics of Molybdenite on Rhenium Resource

Mesozoic molybdenum deposits distributed widely in Fujian province,and associated with a certain amount of rhenium.Based on field systematic investigation and petrography,through studying the characterstics of ore petrology and mineralogy of molybdenite of typical molybnum deposits(Pingdi,Shangxikeng,Luobuling,Makeng,etc.) in Fujian Province,this paper obtain that straint of mineralogical characterstics of molybdenite on Re resource reflect in the action of temperature,the molybdenite formed under the medium-high temperature has a high degree of crystallinity,coarse grain,in sheet or plate,2H polymorph mainly,strong pleochroism,low content of trace elements and Re;the molybdenite formed under the low-medium temperature has a low degree of crystallinity,fine grain,in tiny scale,2H+3R or 3R polymorph mainly,weak pleochroism,high content of trace elements and Re.As a kind of accompanying elements,Re is of some comprehensive utilization value.
