Jun 15, 2019· The tests were carried out at room temperature (20–22 °C). During the flotation process, the airflow was set at 0.27 m 3 /h and the froth was recovered at 2 s intervals for 3 min. All the tests were realized with 200 g/t RBD15. The depressant concentrations were adapted so that only the most significant results are presented in this paper.


Abstract: In this study, there is 1.42% P2O5 in the P-containing V-Ti magnetite tailings in Miyi Region of China, with the valuable minerals mainly including apatite, and aluminosilicate minerals as the main gangue components. The direction flotation process was used to recover phosphorous from the low-grade phosphorous-bearing V-Ti magnetite ...

May 30, 2016· The feed sample, with 57.20% Fe, 6.42% SiO 2 and 0.748% P was mainly composed of haematite and magnetite and the main gangue minerals were apatite and quartz. The results of flotation tests showed that sodium silicate performed better as depressant of iron oxide, but had little effect on silica flotation in the apatite–iron oxide–silica ...


demonstrating its role as magnetite depressant in flotation. The presence of non-ionic surfactant enhanced the Atrac flota-tion of apatite with no flotation of magnetite. Bench-scale flotation tests showed that 50% of Atrac can be replaced with non-ionic collector without impairing the flotation results.


The apatite ore body at Beldih occurs as apatite-quartz-magnetite vein. Mineralogical examination indicated the presence of apatite as the chief phosphate bearing mineral while the major interfering iron oxide bearing mineral are magnetite, hematite, goethite limonite in association with quartz, chert and sporadically occurred pyrite.
