Immobilizing chromium in stainless steel slags with MnO addition

Zhanjun Wang et al.

Summary: The study found that MnO can stabilize Cr in stainless steel slags by forming MnCr(2)O(4) spinel phase, reducing the leaching tendency of hazardous Cr-related ions. Thermodynamic calculations indicated that the MnCr(2)O(4) spinel phase was relatively stable, while the Ca3Si2O7 phase was relatively unstable compared to other crystal phases.

Understanding the solidification and leaching behavior of synthesized Cr-containing stainless steel slags with varying Al2O3/SiO2 mass ratios

Zhanjun Wang et al.

Summary: This study examined the impact of Al2O3/SiO2 mass ratios on the crystallization behavior of stainless steel slags and the leaching stability of Cr-containing slags. The results showed that adding appropriate amounts of Al2O3 could help stabilize Cr in the primary spinel phase, reducing leaching of Cr into the environment.

Cyclic metallurgical process for extracting V and Cr from vanadium slag: Part I. Separation and recovery of V from chromium-containing vanadate solution

Xue-wen Wang et al.

Summary: The cyclic metallurgical process investigated the separation and recovery of V from chromium-containing vanadate solution through selective precipitation, leaching, and preparation of V2O5. The addition of Ca(OH)(2) and ball milling improved the precipitation efficiency and leaching rate of V. The final product of V2O5 with 99.6% purity was obtained through leaching with NH4HCO3 and calcining at 560 degrees C.
