| titleOfInvention | Apparatus for refining metal concentrates |
| abstract | ABSTRACT OF THE DISCLOSURE Novel apparatus is provided for carrying out the process of separation of both base metal and silver from precious metal components in mineral concentrates. The apparatus comprises (a) a tubular burner, (b) means for discharging a hydrogen-chlorine flame in said tubular burner into an inner heat-resistant tube, (c) means for the passage of the said mineral concentrates in particulate form through the reaction-zone of said hydrogen-chlorine flame, (d) means for maintaining said reaction zone at a temperature within the range of 900°C to 2500°C, and (e) means for scrubbing the reaction products after passage through said flame with an aqueous solution. The use of this apparatus provides a treatment of the raw material concentrate with reacting hydrogen and chlorine gases at elevated temperatures, which renders the precious metal-containing residue soluble in oxidising hydrochloric acid solution. |
