Short summary
Vanadium ores from the Bushveld Complex contain distinct microscopic mineral textures that strongly influence how efficiently vanadium can be extracted. Our study shows that some textures tightly intergrow minerals and hinder separation, while others form coarser structures that improve processing by magnetic and flotation methods. Identifying these textures is essential for optimizing vanadium ore processing and resource use.
