Abstract: For studying the low-grade wolframite and scheelite ore of WO₃ grade of 0.23%, according to the principle process of mixed floating wolframite and scheelite -Peter Lavrov law separation of scheelite -Shaking table fractionated recovery of wolframite,suitable grinding fineness and the appropriate amount of reagent were studied.The final available WO₃ grade of scheelite concentrate, wolframite concentratel, wolframite concentrate 2 is 65.43%,50.11%,31.65% respectively, and recovery each is 51.21%,26.14%,13.76%,total recovery of tungsten is 91.11%.
