02 Wolframite grinding stage. Because the tungsten is brittle and has a significant ratio, which is easy to cause overgrinding and overcrushing in the grinding process, and produce too much secondary slime. Therefore, the grinding stage is particularly important in the tungsten ore extraction process.
