1. Introduction. Flotation separation has been widely used in the process of ore dressing because of its high separation efficiency and economy (Chen et al., 2021a, Liu et al., 2021, Wang et al., 2021a, Xie et al., 2020b).Selectively adsorbing appropriate collectors on the surface of valuable minerals will enhance the difference in …

Lepidolite, crucial for lithium extraction, is primarily processed through flotation. However, conventional flotation inhibitors pose environmental challenges. This study introduces Fe(III) as a selective and eco-friendly inhibitor in lepidolite flotation. We investigated its impact on flotation performance and interaction mechanisms with …
In this study, the flotation separation of spodumene from feldspar was achieved using mixed collector of sodium oleate (NaOL)/cetyl trimethylammonium bromide (CTAB). Micro-flotation experiments show that the selective flotation separation of the two minerals could not be achieved in the presence of single collector under the pH …
Potassium feldspar and quartz are all silicate minerals with frame structure,and have the similar crystal structure and physicochemical properties. Therefore, flotation has become the main method to separate potassium feldspar from quartz. The separation of potassium feldspar from quartz with anion and cation mixed collector was studied in …
This study demonstrates a high froth flotation separation selectivity between quartz and feldspar and that quartz can be readily floated in diluted HF solutions with …
