leaching and adsorption for vanadium ore newest design

Leaching Kinetics of Vanadium with Electro oxidation and

A residue containing vanadium and chromium was precipitated from a wastewater mill. Electro oxidation technology and H2O2 acting as reinforcement methods were introduced for vanadium leaching from the residue. During the leaching process, sodium hydroxide could provide an appropriate reaction medium and promote the reaction rate of the acidic oxides.

Minerals Free Full Text Vanadium Bioleaching Behavior

This study investigated bioleaching behavior of vanadium from a vanadium bearing shale using Acidithiobacillus ferrooxidans (A. ferrooxidans). Results showed a maximum recovery of 62% vanadium in 1.2 day bioleaching, which was 22.45% higher than the controls. Then, the vanadium leaching efficiency decreased significantly, only 24% of that was obtained on the tenth day.
