Chromium-bearing vanadium slag contains vanadium,chromium and other metals which are important national strategic resources.However,they are toxic to human health,so it is significant to dispose them.Clean utilization route of chromium-bearing vanadium slag with high added value in phosphorus chemical industry is introduced in this paper.Key technologies are also researched,including research and development of new extraction system,mechanism of extraction,formation mechanism and control of the middle layer.On this basis,a seamless link between extraction and upstream and downstream units is realized,which results in a technology package of comprehensive utilization of all components in chromium-bearing vanadium slag.Furthermore,a 15 000 t/a demonstration project has been built and significant economic,social and environmental benefits have been achieved.
