Research and Application of Room Temperature Flotation Process for a Scheelite Mine in Hunan Province
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.
