Almost 29.57–38.46 million tons of zinc-bearing dust were produced in Chinese iron and steel enterprises annually. The recovery of Zn and other metals in zinc-bearing dust from ironmaking and steelmaking could improve economic efficiency. However, zinc-bearing dust was classified as hazardous waste, and the volatile metals (like Zn, Na, Pb, etc.) in …

Havlik et al. [15] investigated the extraction of zinc from electric arc furnace dust using dilute sulfuric acid, obtaining a zinc extraction rate of 65 % under optimal conditions. Hydrometallurgical processes can obtain a high iron recovery rate and zinc removal rate, but the leaching agent consumption is higher, and the leaching residue is ...

An in situ polyaniline (PANI) intercalation strategy is developed to facilitate the Zn2+ (de)intercalation kinetics in V2 O5, exhibiting a stable and highly reversible electrochemical reaction during repetitive Zn 2+ insertion and extraction. Rechargeable zinc‐ion batteries (ZIBs) are emerging as a promising alternative for Li‐ion batteries. However, the …

Zinc ferrite (ZnFe2O4), one of the major forms of zinc in electric arc furnace dust and zinc leaching residue, is very difficult to chemically dissolve in either acidic or alkaline solutions. It is therefore necessary to study the extraction of zinc from zinc ferrite to achieve the full recovery of the zinc resources. In this paper, CaO was used to degrade the structure of …

The reversible intercalation of ions into manganese dioxide was first reported in an aqueous system and a large capacity was measured. A cycle life test was performed at, and after, no capacity fading was found, which indicates the good cycling properties of manganese dioxide toward the insertion of zinc ions.X-ray photoelectron spectrum measurements …

The roasting reaction product (Ca 2 Fe 2 O 5) do not participate in the leaching reaction, eventually Ca 2 Fe 2 O 5 exist in ammonia leaching residue which can be used as sintering raw material and steelmaking solvent. After processing, zinc leach liquor can be used as raw material of zinc electrodeposition. In consequence, comprehensive utilization of iron …
