How to upgrade scheelite? And what grade of tungsten can ...

2020-7-27 · For scheelite tungsten ore, floatation separation is used very commonly due to its great floatability. Rough floatation separation and fine selection has been included in the floatation separation of scheelite. Rough floatation separation is to remove the waste to the largest extent with a good recovery while the fine selection is the key to get high grade scheelite tungsten concentrate.
