I am studying abroad and urgently need information related to the research on \"recovering vanadium and copper from copper-vanadium slag after vanadium removal in titanium tetrachloride production.\" I would appreciate it if colleagues could help me. My email address is: lanzlyl@163.com
You might want to take a look at magazines such as \"Foreign Vanadium Metallurgy\", \"Vanadium and Titanium\", and \"Vanadium Extraction in Steelmaking\"; they might be useful to you
Copper and vanadium are first leached with sulfuric acid, followed by selective precipitation through extraction or pH adjustment.
Copper and vanadium are leached using sulfuric acid, and the pH value is adjusted to 2-3 with ammonia to precipitate orange-colored ammonium polyvanadate. Copper is recovered through electrolysis of the copper-containing solution, while ammonium polyvanadate is calcined in an oxidizing atmosphere at 450-550 degrees Celsius to decompose into vanadium pentoxide. Vanadium pentoxide is then melted with aluminum to form an alloy, which is subjected to multiple vacuum degassing processes at 1790 degrees Celsius; as a result, vanadium ingots with 99.9 purity can be obtained.
