Title: Experiment research on mineral processing of recycling wolframite and scheelite from a low grade polymetallic ore
Abstract: A complex and low grade wolframite-scheelite associated ore belongs to a world-class refractory one,which is assaying WO3 0.26% with distribution of WO3 in scheelite,wolframite and tungstite being 82.69%、13.85%、3.46% respectively.And more than 90% of grains size is less than 0.074 mm.However the recovey of WO3 was just 65% after years research.In order to improve recoverage of WO3,a new mineral processing reagent TAB-3 and a reasonable flowsheet(flotation-magnetic separation-flotation) are adopted after experiment research,the scheelite concentrate assaying WO3 74.57% with recovery 69.47% and wolframite concentrate assaying WO3 28.88% with recovery 8.08% are obtained with total recovery WO3 77.55%.
