Testing of New Collectors for Concentration of Fluorite by
In this study, two new collectors for fluorite flotation DPOMC1033 (DPI) and DPOMC1234 (DPII) were tested and compared with oleic acid (OA), sodium oleate (SO) and potassium oleate (PO). According to fluorite grade and fluorite metallurgical recovery, the effect of each collector was determined, both in mechanical and pneumatic cell flotation.
Flotation Separation of Scheelite from Fluorite Using
The depressing properties of sodium polyacrylate (PANa) for scheelite and fluorite were studied by microflotation tests, infrared spectroscopy (IR), zeta potentials, Xray photoelectron spectroscopy (XPS), and density functional theory (DFT). The flotation results reveal that the selective depression effect of PANa is better than that of sodium
Selective flotation of scheelite from calcite and fluorite
A series of flotation results demonstrate that the collector mixture of 733 and MES at a mass ratio of 4:1 achieves the best flotation separation performance, as shown in Fig. 3. Scheelite has a favorable recovery of 70%. However, the recovery of calcite and fluorite are 39% and 1%, respectively. Compared with the results using 733 collector as

Fluorite is an important strategic mineral. In general, fluorite ores will contain a certain amount of calcite gangue mineral. Thus, they need to be separated from each other. For an economic separation,
Activation and mechanism of Cu2+ and Fe3+ in flotation
The results showed that the recovery rate of fluorite reached 83% using sodium oleate as collector under the flotation condition of pH range of 8~10. The fluorite recovery rate increased by 8% and
Selective Flotation of Calcite from Fluorite: A Novel
The results demonstrated a high selectivity for the flotation of calcite from fluorite using this new reagent schedule. The best selective separation for a single mineral and mixed binary minerals was obtained when 200 mg/L of NaF, 50 mg/L of CA, and 6 mg/L of SOA were used at pH 9. In addition, a batch flotation experiment was carried out
