  Key process mineralogy parameters for rare earth …

  2020121 · They are also key parameters for identifying the potential metallurgical beneficiation route and to optimise recovery of the target minerals. Herein we discuss how these mineralogical characteristics can be utilised to predict behaviour in mineral processing and present a possible flowsheet option to process the Songwe Hill deposit. 5.1.

  Beneficiation of fluorite by flotation in a new chemical scheme

  200371 · The most commonly used beneficiation process is froth flotation, producing fluorite concentrates of up to 99% purity. Typically, fatty acid is used as collector in fluorite flotation, and water glass as a depressant of silicate gangues; the ore pulps are heated to 35–85 °C in the system (Crozier, 1992). If the content of calcite, phosphates ...

  Effect of Fluoride Ion on the Separation of Fluorite from …

  20211028 · Although the advantages of metal-ion modifying agents have been confirmed many times, research on the effect of anions on flotation depressants has rarely been reported. In the separation process of fluorite and calcite, fluorine ion is used as the original ion in the solution, which reduces the influence of external ions on flotation.
