| Abstract: | As for the tungsten polymetallic ore in Hunan being characterized by finely disseminated valuable minerals and complicated mineral compositions, there exist problems of the associated tin minerals with a low grade and poor floatability, high cost in flotation recovery of a single tin. Thus, a novel self-developed collector, GYX, was adopted to treat the tailings grading 0.34% WO3 and 0.089% Sn from sulfide ore flotation, after ground to a fineness of -0.074 mm 82.35%. By using a close-circuit tungsten-tin bulk flotation flowsheet consisting of one stage of roughing, three stages of scavenging and five stages of cleaning, a tungsten-tin bulk concentrate grading 38.11% WO3 and 3.87% Sn was finally produced with the corresponding recoveries of 74.05% and 29.74%. It is shown that this approach can achieve the synchronous recovery of tungsten-tin minerals. |
