vanadium slag with waste titanium dioxide without roasting was studied. Mineralogy analysis indicates that the converter vanadium slag contains mainly three mineral phases:magnetite, titanium magnetite, and silicate phase. Vanadium is in combination with iron, titanium, manganese,aluminum, and silicon. The impacts of leaching temperature, leaching time, stirring speed, liquid-to-solid ratio, and initial......
