us3770213a process for separating carbon fromiron

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. Aflotationagent and a forthing agent are added to the slurry. The slurry is vigorously agitated to thoroughly coat the carbon particles with theflotationagent
