Purification Of Specularite By Centrifugation Instead Of ...

A widely used technology for recovering iron from complex mines and fines is froth flotation, particularly reverse flotation [7, 27 – 28]. The reverse flotation of iron ore occurs at the pH of 8–11, and the gangue mineral (mainly quartz) is recovered in the foam phase with the amine collector [29 – 30]. Dodecylamine is currently the most ...

Froth flotation is a physico-chemical separation process. Separation is principally based on differences in surface hydrophobicity. However, particle size and density have a significant impact. Initial flotation patent and application was developed for graphite by the Bessel brothers (1877). Similar to graphite, coal is naturally hydrophobic.
