研究了氯化钠 -硫氰酸铵 -结晶紫体系浮选分离锌 ( )的行为 .研究表明 ,在水溶液中 ,Zn( )与NH4SCN、结晶紫 (CV)生成三元离子缔合物沉淀 [Zn(SCN) 2 -4]· (CV+ ) 2 .在少量 Na Cl存在下 ,该沉淀能很好地浮于水相表面并和水完全分离 .在水相 p H值为 1～ 4时 ,通过浮选可使 Zn( )与 Fe( )、Al( )、Ni( )、Mn( )、Cd( )离子的完全分离 .
The behavior of Zn (superscript 3 +) in sodium chloride - ammonium thiocyanate - crystal violet system was studied by means of flotation separation of Zn (superscript 3 +) with NH4SCN and crystal violet (CV) Zn (SCN) 2 -4] · (CV +) 2. In the presence of a small amount of NaCl, the precipitate floats well on the surface of the aqueous phase and is completely separated from the water. When the pH of the aqueous phase is 1 to 4, By flotation Zn () and Fe (), Al (), Ni (), Mn (), Cd () ions completely separated.
