They found that a fraction of more than 0.95 could be removed by continuous ion flotation under the optimum operational conditions. 48 The residual concentration of Direct Red could be lowered to below 0.5 ppm after 3 minutes of treatment by ion flotation when Choi et al. used sodium lauryl sulfate as both collector and frother. 49 Rhodamine B ...

Stibnite froth flotation: A critical review

When added to the flotation pulp, sodium silicate undergoes a complex hydrolysis process that originates a series of ionic and colloidal compounds. The type of compounds formed depends on sodium silicate dosage and the pH of the pulp (Silva et al., 2012). The optimal depressant action of this reagent has been observed in a pH range …

Effect of dissolved fluorite and barite species on the flotation …

Flotation of celestite is inhibited under alkaline conditions when using sodium dodecyl sulfate owing to the specific adsorption of carbonate on the celestite surface [23]. A previous study evidence that the carbonate species reduce the recovery of feldspar with using sodium oleate under strongly alkaline conditions [24].
