Abstract��
Active zinc oxide was produced from crude zinc oxide by using ammonia leaching technique.Manganiferous ions was removed by using H 2O 2 as a oxidant and copper ions was removered by (NH\-4)\-2S in order to purify the zinc complex liquor in the purification process. The experimental results showed that this technological process was suitable for treating zinc complex solution to produce high grade zinc oxide.
