DetailsCA is a small-molecule organic acid and a highly water soluble of tricarboxylic acid has three hydrogen ions that can be ionized in solution. The molecular structure of CA is shown in Fig. 1.As a flotation reagent, CA typically serves as a depressant, and it can also change the pH of the slurry to affect the flotation of minerals.
DetailsThe Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is …
