| Abstract: | A novel method for producing high purity potassium silver cyanide [KAg(CN) 2] by using oxygen blast cyanidation method was introduced.The electrolysis silver powder was used as a silver source and kept excessive in the process of producing KAg(CN) 2.The amount of water evaporated from the solution of KAg(CN) 2 should be controlled strictly so as to obtain high quality product.This method has the advantages of easy-obtained raw materials,simple operation,high purity product,low cost and easy enviromental control.It is suitable for the production of middle/small enterprises. |
