Beneficiation studies of tungsten ores A review

2018-8-15  At a wolframite-scheelite concentrator in China a beneficiation process was developed (Mao et al., 2015) by adding high gradient magnetic separation (HGMS) to the stage of rough bulk wolframite-scheelite flotation to recover wolframite, and the rough wolframite and scheelite concentrates were cleaned separately by flotation in different streams. The wolframite cleaning tailings were returned to the rough flotation

New insights into separating wolframite from calcium

2021-5-25  Wolframite ores are often processed by physical separations, mostly by gravity and magnetic separations, with fine particles suffered serious losses, while flotation is regarded as the effective technique to separate the fine complex wolframite ore from gangue minerals,. China is rich in tungsten reserves and its output ranks first in the world.

2017-1-1  The flotation characteristics and kinetics of fine wolframite from Shizhuyuan Mine, Hunan, China were studied. Coarse and middle particles entered the concentrate easily. However, because of the reduction of middle particles as carriers and the poor collision and attachment between fine particles and air bubbles, it was difficult to float fine particles.
