Recovery of vanadium from hot metal by atomizing process
National First
Recovery of vanadium from hot metal by atomizing process is a proprietary technology independently developed by Pangang. The hot metal in the atomizer was granulated into iron droplets under high pressure. Then operating conditions were controlled in a way that vanadium was oxidized to the greatest extent while carbon was not extensively oxidized so that necessary carbon could be retained in the blown hot metal to provide sufficient heat sources for BOF steelmaking. Remarkable results were obtained in the industrial applications: oxidization of V was 90%, vanadium recovery 66.7%, slag output 4.6%, blown metal yield 94%, carbon content in blown metal 3.5-3.8%. Successful development and application of this technology brought an end to the monopoly over vanadium extraction technology by the foreign countries and made China one of the three largest vanadium suppliers in the world.
