Abstract. The process of pressure leaching the converter 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–titanium magnetite is another major raw material from which to extract vanadium. China’s vanadium–titanium magnetite reserves are huge—up to 9.83 billion tons that reach mineable grade—and are therefore of high utilization value [2,3].
Titanium–vanadium slag obtained by direct reduction of titanomagnetite concentrates containing 40 wt%–50 wt% TiO 2 and 1.5 wt%–2.0 wt% V 2 O 5 is a new and promising type of raw material for both recovery of titanium and vanadium.
The extraction of vanadium and titanium were 91% and 77%, respectively, after roasting at an AS-to-vanadium slag mass ratio of 4:1 and 370 °C followed by leaching in a 6% H 2 SO 4 solution.

The Medcalf project is an exciting titanium/vanadium project located in Western Australia. Unlike other titanium/vanadium projects, the Medcalf project is extremely weathered and requires hydro-metallurgical recovery instead of mineral sands style processing.
