Abstract

Abstract

Aiming at a low-grade vanadium titanomagnetite resource in Xinjiang, an experimental study on efficient comprehensive recovery of iron and titanium benefication was carried out. According to the specific properties of the ore, a technological process of iron and titanium comprehensive recovery was developed, including stage grinding stage selection of iron, strong magnetic preconcentration, and flotation to recover titanium. The iron concentrate product with a yield of 16.43%, a TFe grade of 57.08%, and a Fe recovery of 53.24% was finally obtained from the iron separation process. Ilmenite flotation material products with yield of 23.35%, TiO₂ grade of 16.30% and recovery of 50.22% were finally obtained by titanium separation and preconcentration. The final result of titanium flotation is a titanium concentrate product with a yield of 25.60%, a TiO₂ grade of 48.02%, and a TiO₂ recovery rate of 75.62%. With such good index, this process provides a technical reference for iron and titanium recycling of low-grade vanadium titanium magnetite in such areas.
