Vanadium is not produced from one ore mineral. Titanomagnetite, sandstone-type ores and some industrial byproduct streams require different preparation approaches.
- Source examples
- Titanomagnetite and sandstone-type ores
- Critical distinction
- Iron-titanium matrix and vanadium occurrence
- Preparation objective
- Condition the valuable phase for downstream separation
Why does vanadium ore depend on source type?
Vanadium may be associated with iron-titanium minerals in titanomagnetite systems, while sandstone-type deposits can have different mineralogy and particle characteristics. There is therefore no single vanadium-ore flowsheet.
What does preparation target in titanomagnetite ore?
Crushing and grinding help liberate iron-titanium oxide phases from gangue. Magnetic response can matter in downstream separation, but the required liberation size is established from representative tests.
Why are sandstone-type sources different?
Sedimentary feeds can differ in valuable-phase distribution, clay content and oxidation state. Grinding intensity selected for hard rock should not be transferred directly to this material.
Inputs that should be verified
- Vanadium-bearing mineral or phase
- Iron and titanium minerals
- Feed hardness and particle size
- Liberation behaviour
- Requirements of the downstream separation or metallurgical step
