江苏省冶金局于一九八○年十一月下旬在南京主持召开了锌热酸浸出——喷淋沉淀除铁技术鉴定会。这项科研成果是江苏省冶金研究所和浙江温州冶炼厂试验成功的。 喷淋沉淀法除铁是将含有三价铁的弱酸性浸出液,用喷淋的方式喷入搅拌均匀、含铁小于1(克/升)的溶液,以焙砂为中和剂,在pH4～5、温度85～90℃的条件下,使三价铁快速水解,呈一种结晶良好并有一定粒度的铁沉淀物析出,以达到除铁的目的。
Jiangsu Province Metallurgical Bureau in late November 1980 chaired a zinc hot acid leaching - spray precipitation iron removal technology appraisal meeting in Nanjing. The achievements of this scientific research have been successfully tested by Jiangsu Metallurgy Research Institute and Zhejiang Wenzhou Smelter. Spray precipitation method is a weak acid leachate containing ferric iron, spray spray into the uniform mixing, iron content of less than 1 (g / L) of the solution to calcine as a neutralizing agent at pH 4 ~ 5, the temperature 85 ~ 90 ℃ conditions, the rapid hydrolysis of ferric, was a good crystal and a certain size of iron precipitate precipitation, in order to achieve the purpose of removing iron.
