Abstract

In this study,a sodium silicate base depressant,a BD depressant and a benzyl hydroxamic acid base collector are adopted to process heat flotation tailings in Shizhuyuan plant.The tailings contain 1.74% WO3,by use of one time of rough flotation,three times of scavening,three times of cleaning, wolframite concentrate containing WO3 over65% can be obtained,with a recovery of WO3 over 90%.
