flotation process definition


Flotation – Wikipedia

Flotation är en kemisk process för att separera hydrofoba material från hydrofila, som används bland annat till att rena dricksvatten och anrikning av malm.. Vattenrening. Flotation används i vattenverk som framställer dricksvatten eller rent processvatten för industrier. Processen är effektivare än sedimentering när partiklarna/flockarna är lätta.

flotation process | Infoplease

flotation process, in mineral treatment and mining, process for concentrating the metal-bearing mineral in an ore. Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface.

Flotation Process

Flotation processes are based on the different surface wettability properties of materials (Wang et al., 2015). In principle, flotation works very similarly to a sink and float process, where the density characteristics of the materials, with respect to that of the medium where they are placed are at the base of the separation.
