    Zinc and lead recovery from jarosite residues produced in

    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 ...

    Treatment of Secondary Dust Produced in Rotary Hearth

    For iron-containing dust with high zinc content, the return sintering method cannot be adopted for treatment, because the circulation and enrichment of zinc will affect the sintering efficiency and reduce the life of the blast furnace; presently, it is mainly processed using the rotary kiln or rotary hearth furnace (RHF) [10,11].

    Extraction of Lead and Zinc from a Rotary Kiln Oxidizing

    Since the mixed lead-zinc concentrate was oxidized in a rotary kiln, zinc sulfate and lead sulfate are both present in the roasting cinder. If wet grinding is adopted to change the material size, it is not conducive to the control of the liquid-solid ratio in subsequent leaching tests and the concentration of Zn 2+ in the leaching solution. Furthermore, it is not conducive to the subsequent separation or the recovery of zinc …

  • Speciation of Zinc in Municipal Solid Waste Incineration

    Speciation of Zinc in Municipal Solid Waste Incineration

    Jun 04, 2004 Fly ash is commonly deposited in special landfills as it contains toxic concentrations of heavy metals, such as Zn, Pb, Cd, and Cu. This study was inspired by our efforts to detoxify fly ash from municipal solid waste incineration by thermal treatment to produce secondary raw materials suited for reprocessing. The potential of the thermal treatment was studied by monitoring the evaporation ...
