Separation of bastnäsite from fluorite using ...

2019-4-1  In single mineral flotation experiments, 2.0 g bastnäsite or fluorite was dispersed in the cell with 40 mL distilled water. The pH of the mineral suspensions was adjusted by NaOH or HCl, and then OHA and EDTA (if needed) were added and conditioned for 2 min for each reagent, after that the pH was readjusted. The flotation lasted for 4 min.

A NEW TECHNOLOGY OF SEPARATION OF FLUORITE

This paper described the separation of fluorite from barite by flotation with S-2 as a regulator and C_(235) as a collector. Studies indicated that C_(235) was a good collector for fluorite and S-2 was a selective depressor for barite. Good results of separation of artificial mixturesandthenaturalore were received. The reaction mechanism of S-2 with thesurface of minerals hasbeen studied by ...
