Jul 31, 2021 Generally, we will pre-enrich the crushed ore, and discard the waste rock by hand selection to obtain qualified ore. Depending on the nature of the wolframite ore, some concentrators can use forehand or backhand selection, and some concentrators need to adopt a process that combines forehand and backhand selection. 2 Gravity separation stage
Jan 21, 2002 The ore is first crushed and milled to liberate the tungsten mineral crystals. Scheelite ore can be concentrated by gravimetric methods, often combined with froth flotation, whilst wolframite ore can be concentrated by gravity, sometimes in combination with magnetic separation.
The tungsten ore concentrate is first coarsely processed by a jaw crusher to a suitable particle size, and then uniformly sent to a ball mill for crushing and grinding until it becomes a tungsten ore fine material that satisfies requirements. The tungsten ore is then sent to the next process.
