Influence of different comminution flowsheets on the separation
Vanadium-titanium magnetite (VTM) ore is the main source of V, Ti, but also optimizes the separation of vanadium-titanium magnetite and improves the TiO2 recovery in ilmenite.1. Introduction. The vanadium–bearing titanomagnetite (VBT) is a strategic and complex iron ore, which containing valuable metals of vanadium, titanium, and iron used as constituents of several alloys, whitepigments, and steel [1], [2], [3].In China, the gross reserve of titanium in VBT ore is estimated to be about 1.18 million tons, accounting for Efficient separation of vanadium, titanium, and iron from

Reduction behaviors of vanadium‑titanium magnetite with
The chemical compositions of vanadium‑titanium magnetite ore are presented in Table 1, which were determined by chemical methods combined with X-ray fluoroscopy (XRF). The vanadium‑titanium magnetite ore contained 47.58 wt% Fe, 20.00 wt% TiO 2 and 0.80 wt% V. According to the analysis results of X-ray diffraction (XRD) The black sand magnetite is a raw material to produce iron and steel. High content magnetite in the top meter beach sands of the north-west of El-Burullus Lake of Egypt is separated and mineralogically and geochemically investigated.

Mineralogical reconstruction of Titanium-Vanadium hematite
This is because primary vanadium-titanium magnetite ore is more common in China, while hematite-limonite containing vanadium and titanium are relatively rare [18], As a result, effective separation of titanium minerals and iron minerals was achieved, while the separation of vanadium and titanium was also realized. 2. Materials and methodsThe metallization reduction-magnetic separation process was adopted to carry out the experiments to promote the recovery ratio of valuable elements by adding diboron trioxide additive in this work. It is demonstrated that diboron trioxide has the function of destroying Si–O–Si bond for the reduction of ultra-high-titanium magnetite.The A novel method of enhancing valuable element recovery for
