Abstract

PURPOSE: To separate and recover Zn at a low cost by adding an aqueous ammonium thiocyanate soln. to wet separate Zn as a Zn(SCN)2 soln., crystallizing Zn(SCN)2 by cooling, and carrying out solid-liq. separation.
CONSTITUTION: To a substance contg. Zn such as blast furnace dust or converter dust produced in an iron mill is added an aqueous ammonium thiocyanate soln. such as rhodane waste water discharged from a process for desulfurizing waste gas from a coke oven. They are agitated with an agitator and filtered to extract Zn as a Zn(SCN)2 soln. By cooling this extacted soln., Zn(SCN)2 is crystallized and separated. The crystallized Zn(SCN)2 is oxidized to ZnO, the ZnO is dissolved in an org. acid, and the resulting soln. is electrolyzed to recover Zn.
