The separation and extraction of titanium, iron, and alumina in one spot can shorten the process and make full use of the electric energy. Under optimal conditions, China is rich in total reserves of iron-containing mineral resources; however, the average grade of iron ore in China is not competitive with that in Australia and Brazil [19]. Fixed carbon and volatile matter contents were lower in BFD than those in coal.

Optimized magnetic separation for efficient recovery of V

In contrast, VTM is a multi-metallic iron-based ore containing iron, titanium, and vanadium as the main constituents [24, 25]. Since VTM has a high iron and titanium content, many recovery studies have been conducted from the viewpoint of developing processes for titanium enrichment [26, 27]. Studies on the beneficiation process for The addition of a small amount of iron powder (0.1 kg iron powder for 1 kg ilmenite ore) was proved to largely enhanced the leaching rates of both iron and titanium. When the solid/liquid ratio was increased from 1/20 to 1/8, complete dissolution of both iron and titanium was achieved in 1.5 h with iron powder addition compared with 2.5 h underA literature review of titanium metallurgical processes
