| titleOfInvention | EXTRACTION OF METALS FROM WASTE CONTAINING COPPER AND OTHER VALUABLE METALS |
| abstract | 1. The method of extraction of non-ferrous metals, in particular copper, nickel and cobalt, from metallurgical wastes containing these non-ferrous metals with an oxidation state greater than or equal to zero in an AC plasma electric arc furnace having a group of electrodes and containing a liquid copper bath mirror coated flowing slag, the method comprising at least one smelting and reducing phase (A), comprising the following operations:! A1) loading metallurgical waste containing non-ferrous metals onto a mirror of molten metal contained in a plasma electric arc furnace! A2) melting metallurgical waste in flowing slag at the slag / copper bath interface,! A3) reduction of at least non-ferrous metals to an oxidation state greater than or equal to zero, and! A4) vigorously mixing the molten copper mirror by blowing in an inert gas, preferably nitrogen and (or) argon, so as to avoid crusting, accelerate the reduction reaction and cause the transition of non-ferrous metals soluble in copper to the molten copper mirror. ! 2. The method according to claim 1, in which the recovery (A3) is carried out in the presence of carbon, preferably in the form of anthracite. ! 3. The method according to claim 2, in which the recovery (A3) is carried out in the presence of quicklime CaO. ! 4. The method according to claim 1, in which intensive mixing (A4) of the molten metal bath mirror is carried out by blowing an inert gas through under an electric arc furnace at a flow rate in the range between 40 and 150 l / min ยท t, and preferably between 50 and 100 l / min ! 5. The method according to claim 3, in which intensive mixing (A4) of the molten metal bath mirror |
