Scheelite flotation has run into serious difficulties when it requires separation of scheelite from a carbonaceous gangue. Other calcium-bearing minerals, such as calcite, apatite and fluorite, being semi-soluble salts, all exhibit similar flotation properties as scheelite and usual collectors like fatty acids are too unselective for this purpose.
In this study, the development process of low-grade scheelite recycling technology in Luanchuan area was reviewed, including raw ore properties, beneficiation …
