摘要: Soot produced in the combustion of fuel oil contains valuable metals, such as vanadium and nickel. The soot can be disposed of, and the valuable metals can be recovered, by leaching the soot with an aqueous solution of sulphuric acid, to extract part of the metal content from the soot, combusting the soot thus leached, and leaching the combustion residue with an aqueous solution of sulphuric acid, to extract an additional part of the metal content. The solution produced in this second leaching process is preferably returned to the leaching of the soot. Metals can be recovered in a way known per se from the solution produced in the leaching of the soot.
