| Abstract: | With sulfuric acid, hydrochloric acid and nitric acid, waste high magnetic alloy steel can be dissolved and Fe 2 can be oxidized to Fe 3 . First remove most of iron in the form of iron alum, then remove a little iron and aluminium, titanium, copper with urea; lastly separate cobalt and nickel with NH 3-NH 4Cl and make them into corresponding salts. The rate of recovery of cobalt and nickel is 81.5% and 89.7% respectively. |
