| Abstract: | This paper deals with a study on a new technology that Ammonium thiocyanate was recovered from F.R. desulfuration and decyanation waste liguor by a crystallization method accoding to the NH_4CNS-(NH_4)_2S_2O_3-H_2O System phase aiagram theory,The technological process and feature parameters used in the Study are reported.The effects of test on operating conditions are also discussed. The NH_4CNS obtained is 95%～99.5%pure and the tolal yield is above 60%. |
