Carbon Flotation Froth Flotation (Sulphide & Oxide

As far as graphite, a naturally occurring carbon, is concerned, it has natural floatability and can be floated using kerosene, as a collector and pine oil as a frother. Add these during grinding and adjust pH to alkaline (7.5 to 8) domain before flotation. See if this serves your requirement. U Unterstarm 6 years ago Like

Froth flotation separation of carbon from barium slag

Feb 01, 2021 Froth flotation is a separation method based on the different surface properties of minerals ( Harvey et al., 2002, Sun et al., 2009, Yalcin and Kelebek, 2011, Xia et al., 2019a ). The flotation process is mainly the collision and attachment of hydrophobic particles and bubbles ( Harvey et al., 2002, Nikolaev, 2019 ).

Effect of carbon on Cu/Pb/Zn flotation. Froth Flotation

Regarding to some comments, the best way to deal with naturally floating carbon is by pre-flotation. It should be mentioned that, the pre-flotation concentrate usually is discarded directly to tailings, however this stream contains significant amount of lead and zinc. How can we reduce lead and zinc loss to preflotation concentrate. (unknown)
