Abstract

Solvent extraction of molybdenum (VI) from alkali roasted and water leaching of ferro-molybdenum slag by using TOA and TBP as extractants was investigated. In this study, ferro-molybdenum slags contain about 1 wt% Mo. Before Mo solvent extraction, Mo slags were roasted by sodium hydroxide under 6:1 NaOH-slag mass ratio and 600°C for 2hr produced 99.5% molybdenum leaching efficiency by hot water. And leave impurity metal like Fe, Mg and Ca ions in leaching Raffinate. In solvent experiments, the organic phase is composed of TOA as extractant, TBP as modifier and kerosene as diluent. The effect of solvent extraction efficiency on different parameters such as pH and TOA/TBP concentrations. The result indicated the process was an effective method to separate molybdenum ions from high-impurity ferro-molybdenum slag.
