| description | The invention relates to a zinc leaching residue lead and silver leaching combined reagent. The leaching combined reagent is composed of sodium chloride, 1-butyl-3-methylimidazolium hydrogen sulfate and sodium hypochlorite. Meanwhile, the invention further discloses an application method of the leaching combined reagent, and the application method comprises the following steps: when the zinc leaching residues are leached, firstly adding 1-butyl-3-methylimidazolium hydrogen sulfate, and stirring to react for 5-10 minutes; adding sodium hypochlorite, and stirring to react for 20-30 minutes; and finally adding sodium chloride and stirring for reaction. The method does not need high-temperature high-acid pretreatment, and has the advantages of being high in lead and silver leaching rate, good in selectivity, high in process applicability and small in environmental influence.
本发明涉及一种锌浸出渣铅、银浸出组合药剂，该浸出组合药剂由氯化钠、1-丁基-3-甲基咪唑硫酸氢盐和次氯酸钠组成。同时，本发明还公开了该浸出组合药剂的应用方法，其在锌浸出渣浸出时，先添加1-丁基-3-甲基咪唑硫酸氢盐，搅拌反应5~10min；再添加次氯酸钠，搅拌反应20~30min |
