Description
After some preliminary tests, two leaching stages of fly ash to recover vanadium, molybdenum and nickel were selected. A first stage alkaline leaching of fly ash to recover vanadium and molybdenum followed by a second stage sulfuric acid leaching of the residual ash to recover nickel. The impact of some operational parameters (L/S, leaching temperature, mixing time, and agent leaching concentrations) on the recovery of V, Ni was investigated. Conditions of precipitation of V and Mo from alkaline medium and Ni from sulfuric acid solution were established. (author)
