| titleOfInvention | A kind of method for recovering magnesium fluoride polluted acid by harmless treatment in zinc smelting process |
| abstract | The invention relates to a method for harmless treatment and recovery of magnesium fluoride polluted acid in a zinc smelting process, including: 1) harmless reuse of polluted acid; Seeds, modifiers, demagnesiasing agents, lime, etc., heat up and stir, filter to obtain demagnesium solution and magnesium fluoride concentrate, add tannic acid to the demagnesium solution to precipitate germanium, recover germanium, and filter to obtain germanium tannin Slag and germanium precipitation liquid, tannin and germanium slag are burned to obtain germanium concentrate, and the post germanium precipitation liquid is sent to leaching air for oxygen purification to remove iron and fluorine; 3) air oxidation to remove iron and fluorine after germanium precipitation; 4) iron removal Dechlorination of liquid copper slag after fluorine. The invention achieves the open circuit of magnesium oxide, reduces the harm of magnesium oxide in the hydrometallurgical zinc solution system, and recovers magnesium, fluorine and acid harmlessly; by adding active agent, the problem that high zinc-containing solution is easy to form colloid is solved, and the fluorine is changed. The characteristics of magnesium fluoride slag in high zinc ion solution make magnesium fluoride slag form a spongy structure, which is easy for liquid-solid separation. |
