氯化钠-硫氰酸铵-氯化十四烷基吡啶体系浮选锌

Separation of zinc by a floatation system composed of sodium chloride-ammonium thiocyanate hexadecylpyridinium chloride monohydrate

在水溶液中 Zn( )与硫氰酸铵、氯化十四烷基吡啶形成不溶于水的三元缔合物 ,在少量氯化钠存在下 ,此三元缔合物沉淀浮于水相上层并与水分成界面清晰的两相。分相过程中 Zn( )被定量浮选 ,实现了 Zn( )与 Fe( )、Co( )、Ni( )、Mn( )、Cd( )、Al( )

In the aqueous solutions,Zn(Ⅱ) precipitates with ammonium thiocyanate and hexadecylpyridinium chloride monohydrate In the presence of sodium chloride the precipitate is floated It shows that Zn(Ⅱ) can be completely separated from Fe(Ⅲ),Co(Ⅱ),Ni(Ⅱ),Mn(Ⅱ),Cd(Ⅱ),Al(Ⅲ) by floatation The method has the advantage of using non toxic inorganic solvent,simple,rapid and economical
