采用选择性溶解方法对铜合金废渣中的锡进行富集和分离。使用HNO3溶液溶解铜合金废渣,渣中的锡不会溶解从而使其从中得到分离。通过离心分离生成的 H2SnO3沉淀相,然后经过干燥加热生成 SnO2粉末。对SnO2粉末的相组成、表面形貌和化学成分进行分析。
採用選擇性溶解方法對銅閤金廢渣中的錫進行富集和分離。使用HNO3溶液溶解銅閤金廢渣,渣中的錫不會溶解從而使其從中得到分離。通過離心分離生成的 H2SnO3沉澱相,然後經過榦燥加熱生成 SnO2粉末。對SnO2粉末的相組成、錶麵形貌和化學成分進行分析。

Preliminary study on concentration and separation of tin (Sn) from copper alloy dross by selective dissolution method was conducted. The tin in the copper alloy dross did not dissolve in an aqueous nitric acid solution which could allow separation of tin from the copper alloy dross. The tin as H2SnO3 (metastannic acid) phase was precipitated in the solution with centrifuging process and transformed to tin dioxide (SnO2) after drying process. The dried sample was heat-treated at low temperature and its phase characteristics, surface morphology and chemical composition were investigated.
