Description The recovery of iron and vanadium from copper reverberatory slags and ferrophosphorus by pyro and hydrometallurgical techniques has been studied. An induction furnace was used for the pyrometallurgical operations. Reverberatory slog and ferrophosphorus were melted with Ca0, Fe203 and Si02 fluxes in a silicon carbide crucible. The iron produced thus, was refined with similar fluxes in a magnesia crucible. An iron button containing 98.51% Fe, 0.89% Cu, 0.07% Cr. and 0.46% P was obtained with a 95.90% total recovery. Practically 100% of vanadium and 90.5% chromium were oxidized by Fe203 and were recovered in the first step slag. This slag was crushed and ground to -100 mesh and leached with 2% sulfuric acid. Vanadium and chroium were extracted into the leach solution with 100% and 95% efficiencies respectively. Vanadium was extracted from the leach liquor by using tertiary amine (Alamine 336) and stripped with sodium carbonate. The economics of the process were found to by very favorable.
