Carbon particles can be separated from iron oxide particles and other gangue particles contained in blast furnace flue dust. The blast furnace flue dust is mixed with water to form a slurry containing 50 percent to 70 percent solids. A flotation agent and a forthing agent are added to the slurry. The slurry is vigorously agitated to thoroughly coat the carbon particles with the flotation agent.

entrainment. The froth structure changes during batch flotation because of the varying solids concentration in the froth. Early in the test the froth solids concentration is high (i.e. low water content in the froth), and as the test progresses, the froth solids concentration decreases because of less floatable minerals being present.
