Method for producing copper metal from copper concentrates without generating waste |
| abstract |
A method for producing copper metal from copper concentrates without generating waste by: (a) oxidizing copper concentrate; (b) cleaning and cooling the gases; (c) feeding to a reduction reactor; (d) cleaning the gases; (e) discharging hot powders and calcines into water; (f) performing magnetic separation; (g) thickening and filtering the magnetic fraction; (h) floating silica and inert materials; (i) thickening and filtering the silica and inert materials; (j) thickening and filtering the final concentrate containing the copper metal and noble metals; (k) smelting the final concentrate of copper and noble metals; and (l) recirculating ground smelt slag to a roasting reactor. |
