研究了氯化钠 -硫氰酸铵 -十六烷基氯化吡啶 -水体系浮选分离锌 ( )的行为及其与常见离子分离的条件。结果表明 ,在 1.0 g固体 Na Cl存在下 ,当硫氰酸铵 (0 .1mol/L )和十六烷基氯化吡啶(0 .0 1m ol/L)溶液的用量均为 2 .0 m L 时 ,控制 p H值为 4.0 ,Zn( )可被该体系浮选 ,而 Cd( )、Co( )、Ni( )、Mn( )、F e( )、Al( )不被浮选 ,可实现 Zn( )与这些离子的定量分离 ,对合成水样的定量浮选分离 ,结果满意 The flotation separation of zinc (Ⅲ) by sodium chloride-ammonium thiocyanate-cetylpyridinium chloride-water system and the conditions of its separation from common ions were studied. The results showed that when 1.0 g of solid NaCl was used, when the amount of ammonium thiocyanate (0.1 mol / L) and cetylpyridinium chloride (0.100 mol / L) solution were both 2.0 m L, the control p H value is 4.0, Zn () can be flotation of the system, while Cd (), Co (), Ni , The quantitative separation of Zn () and these ions can be realized, and the result of the quantitative flotation separation of synthetic water sample is satisfactory
