In China, the main beneficiation of wolframite is combined beneficiation process based on gravity concentration, and its sorting operations segments are generally divided into roughing, gravity concentration, selection and slime treatment.

 

 

In roughing, based on the principles that "early retrieve and more, early lost and lost more", make wolframite retrieve as soon as possible after dissociation, which is an important measure to improve the recovery rates of tungsten. Some wolframite mines separately elected tungsten block and rich intergrowth in hand-selected operation, directly into the selection of operations, to avoid mud of job loss of the high-grade tungsten block and crushing, grinding, gravity concentration  and other aspects of the transport belt to achieve the "early retrieve and more" to improve the tungsten recovery. In Pangushan, Dajishan tungsten ore roughing process, it used a combination of these types of technology to improve the recovery of tungsten, reducing the loss of the rougher sections of tungsten.
