Abstract
A method is provided of continuously producing and recovering metallic chlorides. The method comprises melting an impure nickel matte in a melting zone, removing the melted product from the bottom of the melting zone, conveying the melted product to a separate chlorination zone sealed from the atmosphere, continuously injecting gaseous chlorine into the melted product in the chlorination zone, maintaining the melted product in the chlorination zone at a temperature such that at least one metal chloride is produced in the vapor phase, discharging the at least one metal chloride into a condensation zone, diluting and cooling the at least one metal chloride in the condensation zone in a continuous flow of cooling gas consisting of sulphur vapor at a temperature and rate of flow such that the temperature is lower than the melting point of the at least one metal chloride and the at least one metal chloride is thereby condensed, collecting the condensed metal chloride and continuously cooling and recycling the cooling gas to dilute and cool further quantities of chloride vapor.
