Vanadiumcorp's 100% owned Lac Dore Vanadium Project is subject to a preliminary economic assessment focused on production of vanadiferous titanomagnetite concentrate "VTM"
Vanadiumcorp is developing a breakthrough method of direct production technology for VE, Fe and TiO2 pigment production from VTM using electricity rather than heat that reduces energy costs and eliminates greenhouse gas emissions.

September 2nd, 2016 - PYROMETALLURGICAL & HYDROMETALLURGICAL PROCESSING OF VANADIUM FEEDSTOCK'S
MONTREAL, QC – September 2nd, 2016 – We are pleased to announce that we have completed last summer a testing campaign for the processing of vanadium rich feedstocks from various origins such as vanadium-rich slag, vanadiferous titanomagnetite, and vanadium-rich residues. Electrochem Technologies & Materials Inc. was selected because our strong know-how in molten salts and high temperature alkaline processing capabilities. The campaign consisted first to perform the pyrometallurgical treatment of 25-kg batches of raw materials by soda ash roasting, alkaline roasting and salt roasting using our 12-kW kiln. The roasted or sintered material underwent hydrometallurgical operation units such as alkaline and acid leaching using counter current cascade leaching reactors and producing 75 liters per batch of pregnant leach solution (PLS). Afterwards, vanadium was precipitated from the PLS either as ammonium metavanadate (NH4VO3) or hydrated vanadium pentoxide (V2O5.250H2O). Finally at the end of the campaign, our patented electrowinning technology was used to recover either metallic iron or an iron-vanadium deposit from the sulfate based pregnant leach solutions while regenerating concentrated sulfuric acid to be reused back in the process. This campaign was to some extent in line with the expertise that was developped in-house over the years by our company for the metallurgical and chemical processing of refractory metals of group VB(5) (V, Nb, Ta) and group VIB(6) (Cr, Mo, W).
