The flotation tests were carried out using a 2 m high continuous column flotation cell which facilitated the generation of a deep froth, since this was the phase of most interest.

The primary collectors used in industrial spodumene flotation are anionic fatty acids, such as tall oil fatty acids (TOFA), which typically contain > 95% oleic and linoleic acid (Kraton Corporation, 2021). These are considered strong collectors with poor selectivity and significant frothing power ( Bulatovic, 2007 ).

After the single factor flotation tests were completed in a previous work and major process parameters and their operational range were identified, statistical evaluation and optimization of reverse nanobubble hematite flotation was conducted with a three-factor and three-level Box-Behnken experimental design using the "Design Expert" …

The findings demonstrate that altering the flow field pattern enhances the turbulence in the flotation machine's mixing zone, enhances the velocity distribution of the three-phase fluid at the bottom of the flotation tank, and fosters bubble-particle contact, collision, and adhesion. This can successfully reduce the clean coal ash content.

Response surface methodology (RSM) is one of the most effective tools for optimizing processes, and it has been used in conjunction with the Analysis of Variance (ANOVA) test to establish the effect of input factors on output factors. However, when this methodology is used in mineral flotation, its polynomial model usually performs poorly. …
