The influence of pulp pH, dispersants, and auxiliary collectors on reverse flotation of carbonatecontaining iron ores was explored. Interactions between iron ores and quartz were theoretically analyzed by flotation solution chemistry and DLVO theory. The results indicated that the iron concentrate grade improved sharply when pH increased from to but changed unobviously when pH was ...

· One such development is the reverse flotation in which the gangue is floated by use of suitable reagents while the valuables remain in the suspension and collected as product/concentrate. This method is completely opposite to the direct or conventional flotation and hence is termed as reverse flotation.

The flotation behavior of quartz, hematite and magnetite under αBLA reverse flotation system were investigated and the separation mechanism of quartzirons was studied by contact angle, zetapotential and infrared spectroscopy. The results showed that the optimum flotation pH was for quartz, for hematite and for magnetite.
WhatsApp During the reverse anionic flotation process, quartz particles attach to air bubbles and float upward into the froth layer leaving iron minerals as sink fraction (Frommer,1964; Birinci et al., 2010). Currently, new type collectors αBromodecanoic acid (CH 3 (CH 2) 7CHBrCOOH, αBDA) (Luo et al., 2015) and αBromolauric acid (CH 3 (CH 2) 9CHBrCOOH, αBLA) (Zhu et al., 2015) were synthesized ...
