    It is seen in Figure 1 that the main phases in the residues are iron hydroxide, zinc hydroxide, goethite, and jarosite. By examination of the zinc calcine leaching process in zinc metallurgy, lead in the residues is thought to exist as lead sulfate [].Coke powder (Shaanxi Longmen Steel, China) with particle size less than 76 μm was added to the residues as reducing agent

    A Review on Recycling and Reutilization of Blast Furnace

    Jun 03, 2021 A large amount of dust is formed as one of the primary by-products during the blast furnace ironmaking process. Besides iron and carbon, it contains a variety of valuable metals such as zinc, lead, and indium widely applied in many industry fields. However, it is difficult to recycle and reutilize blast furnace dust (BFD) due to complex composition, fine particle size, and strong hydrophobic
