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

2013-2-1 Highlights Review conducted of RE mineral beneficiation using English and Chinese language sources. Of the 250 known RE minerals only bastnäsite, monazite and xenotime are extracted commercially. Flotation, using fatty acids or hydroxamates, is the primary separation process for RE minerals. Currently, optimal beneficiation processes employ flotation, gravity and magnetic separation.

An iron ore contains specularite and hematite which are its main iron minerals and carbonates such as calcite which are its main gangue minerals. The ore is very apt to produce slime in the grinding process，leading to a deteriorated beneficiability. The rough iron concentrate can be obtained by using high gradient magnetic separator to discard tailings with the grinding fineness of 95% -0.074mm.
