NOVEL FLOTATION PROCESS OF HIGH-CALCIUM SCHEELITE

The invention provides a flotation process for high-calcium scheelite. Compared to other methods, it has better separation effects, a simpler process, and is more environmentally friendly. It includes crushing and grinding, closed-circuit flotation, and fluorite flotation. In the first step, raw ore is crushed and ground to 55-90% -0.074mm.

In the second step, a closed-circuit flotation process is carried out.
