| titleOfInvention | A kind of method for cooperateing with coordination to reclaim zinc in oxysulphied zinc ore |
| abstract | The present invention relates to a kind of method for cooperateing with coordination to reclaim zinc in oxysulphied zinc ore, belong to technical field of wet metallurgy.First paragraph acidifying oxidation：To oxysulphied zinc ore according to liquid-solid ratio be 2:1~10:1ml/g adds C（H + ）In 5 ~ 10mol/L dilute acid solns, then to add oxidant, 0.5 ~ 1h is leached under the conditions of temperature is 20 ~ 50 DEG C；Second segment coordination is leached：According to C in solution to after being acidified Oxidation Leaching through first paragraph（NH 4 + ）：C（H + ）For 2：1 adds ammonia spirit, and ammonia spirit is identical with the volume that dilute acid soln is added, and continues to leach 0.5 ~ 1h under the conditions of temperature is 20 ~ 50 DEG C, solid-liquor separation obtains zinc lixiviating solution and leached mud after the completion of leaching.The features such as this method possesses that leaching rate is high, polluted less, the time is short. |
