Abstract

PURPOSE: To recover Zn at a low cost by adding an aqueous ammonium thiocyanate soln. to wet separate Zn as a Zn(SCN)2 soln., oxidizing Zn(SCN)2 obtd. by crystallization under cooling to ZnO, and adding S2- ion to filtrate after the crystallization to recover ZnS.
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 extracted soln., Zn(SCN)2 is crystallized and separated. The separated Zn(SCN)2 is oxidized to ZnO. On the other hand, a sulfur compound producing S2- ion such as H2S is added to filtrate after the separation to separate and recover the residual Zn as ZnS.
