主　　题：Scheelite XRT sorting Mixed collector Sustainability 

摘      要：Nowadays,with the depletion of high-grade scheelite resources,the efficient exploitation of complex,low grade with complicated geological structure scheelite ore have to take into *** work introduces a feasible mineral processing method for the beneficiation of low grade and complex scheelite using the X-ray transmission(XRT) pre-concentration technology and mixed *** results of XRT sorting shown that 94.85% WO_(3) can be recovered with the discarding rate reached40.62%.The closed-circuit flotation of actual ore using mixed collector obtained scheelite concentrate of 61.09% WO_(3) grade with WO_(3) recovery of 89.49%.The combined flowsheet of XRT sorting and mixed collector brought about RMB 4.5 million yuan profit per year for the mine company.
