Recovering Method of high purity Tin from low Tin solution by cyclone electrowinning

The present invention relates to a method to recover tin using a cyclone electrowinning device. In detail, impurities are removed from a tin-containing waste liquor, an organic substance, or the like; is removed by an ion-exchange resin method to prepare a tin-adsorbed ion-exchange resin; the ion-ex...

Zusammenfassung:	The present invention relates to a method to recover tin using a cyclone electrowinning device. In detail, impurities are removed from a tin-containing waste liquor, an organic substance, or the like; is removed by an ion-exchange resin method to prepare a tin-adsorbed ion-exchange resin; the ion-exchange resin is treated with a picking solution to obtain a low-concentration tin compound solution; an anti-oxidant is added to the low-concentration tin compound solution; and thereafter, a tin metal is recovered using a cyclone electrowinning device. In the present invention, when compared with an existing tin recovery process, costs for tariff is reduced and a high-purity tin metal is able to be recovered. 본 발명은 싸이클론 전해채취장치를 이용한 주석 회수방법에 관한 것으로서, 좀 더 구체적으로 설명하면, 주석 함유 폐액으로부터 불순물을 제거한 후, 이온교환수지법으로 유기물 등을 제거하여 주석이 흡착된 이온교환수지를 제조한 다음, 이로부터 산세액으로 처리하여 저농도 주석화합물 용액을 얻고, 저농도의 주석화합물 용액에 산화방지제를 첨가 후 싸이클론 전해채취장치를 이용하여 주석금속을 회수하는 방법에 관한 것이다. 이러한, 본 발명은 기존의 주석 회수 공정에 비해 공정운임 비용을 절감할 수 있으며, 고순도의 주석금속을 회수할 수 있다.
