Tungsten Oxide

In our country the white tungsten deposit is mostly a skarn shape deposit, this kind of characteristic of scheelite ore bed is “lean, multiple, thin, miscellaneous”, especially the “miscellaneous”, caused a variety of obstacles to white tungsten ore dressing. Most white tungsten deposit are associated with calcite, fluorite, barite, such as calcium containing gangue, because of the flotability is close to scheelite so is hard to separate. For many years Petrov method is commonly used for the white tungsten flotation method, namely high temperature flotation process, this process must be heating flotation, high energy consumption, the operation is complicated. Following the development of the technology, finally developed a flotation process at room temperature in the 70s.The most representative of flotation process at room temperature is 731 flotation method at room temperature and method of lime, here’s to emphatically introduce lime method. Scheelite flotation pro...
