In order to solve the problems of high environmental pressure and high production cost existing in the process of heated flotation,a scheelite mining enterprise has carried out small-scale and industrial tests of scheelite flotation at room temperature.Un-der the condition of 0.38%raw ore WO3 grade,a flotation index of 46.57%concentrate WO3 grade and 88.78%recovery rate was obtained in a small-scale experiment.Under the condition of raw ore WO3 grade of 0.265%,industrial experiments obtained pro-duction indicators of concentrate WO3 grade of 44.32%and recovery rate of 86.88%.This article also analyzes the cost advantages of room temperature flotation and the problems and countermeasures in industrial experiments.
