    1 Froth Flotation – Fundamental Principles

    1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and

    Jun 02, 2016 Coarse and Fine Particle Flotation Recovery. In The Days of gravity concentration, the art of ore dressing developed on the cardinal principle of saving the values at as coarse a size as possible. Flowsheets were designed which featured an alternation of crushing and concentrating operations. Thus an ore might be crushed to inch, jigged to yield a finished concentrate and a middling; the latter being recrushed to inch
