石灰法常温浮选低品位白钨矿的工艺研究
Technical Research on Flotation of the Low-grade Scheelite at Normal Temperature by Lime-based Method
摘要
Abstract
The WO3 grade of the low-grade scheelite is 0. 39% . By adopting the lime-based methoel for the flotation and separation at the normal temperature,through the roughing closed-circuit test,the rough concentrate of scheelite with the grade of 3. 53% and the recovery of 77. 01% was obtained. Through the open-circuit test, the concentrate with the grade of 42. 12% and the recovery of 46. 26% was obtained by adding the acidized sodium silicate. The XRD spectrum analysis for the product of concentrate showed that fluorite and calcite were inhibited on the stages of roughing by lime-based method and cleaning respectively,realizing the separation of scheelite and calcareous gangue minerals effectively. This study showed that lime method is an effective way to realize the Scheelite Flotation at room temperature.关键词
