· Various attempts have been made in Sweden to recover vanadium from the BOF-slag. In one of the most recent projects a method called IPBM (In-Plant By Product Melting) for carbothermal reduction of BOF-slag using a DC-furnace with hollow electrode was developed at Swerea MEFOS. The aim of the project was to remove vanadium from the slag and make it useable outside the steel plant. The ferroalloy obtained from the slag reduction contained about 10mass V 5-6mass Mn and 1mass P corresponding to a vanadium recovery of more than 90 . The vanadium content of the residual slag was in general between 0.5-1mass .
