Research Status of Spodumene Flotation: A Review
Beneficiation methods of spodumene include magnetic separation, gravity separation, and flotation. Since the major gangue minerals of spodumene are quartz and feldspar, flotation becomes the most important way to concentrate spodumene. In this paper, various researches related to spodumene flotation were reviewed.

Effects of metal ions on the flotation separation of …
Therefore, although Fe(III) effectively improved the flotation of spodumene, it was not beneficial for the flotation separation of spodumene from feldspar and quartz. When Ca(II), Mg(II), and Cu(II) were used as activators, the adsorption amounts of α-BDDA on spodumene were significantly higher than those on feldspar and quartz, which led to …
Review Surface nanobubbles and their roles in flotation of …
The collision between particles and bubbles is governed by their sizes and the hydrodynamic environment in the flotation cell. Yoon and Luttrell derived a functional relationship relating the probability of collision to the sizes of particles and bubbles and the hydrodynamic conditions [19]: (1) P c = 3 2 + 4 R e 0.72 15 R p R b 2 where P c is the …
Feldspar Beneficiation & Flotation Process
The problem in feldspar flotation is to recover slime free granular products, all minus 20 mesh, usually with not over 10% finer than 200 mesh. Flotation under these conditions is critical and pulps are abrasive as well as corrosive. Action of the feldspar pulp must be counteracted by proper selection of equipment to withstand these conditions.
