Thermodynamic analysis on the reduction of iron and chromium in vanadium-extracted waste slag by biomass

Abstract

In this paper, the feasibility of carbon thermal reduction of vanadium-extracted waste slag with biomass as reducing agent was studied via thermodynamic analysis. The effects of oxygen absorption ratio, temperature and basicity on the reduction results, especially on the recovery of valuable metals (iron and chromium) were discussed emphatically.
