Abstract
PURPOSE: To facilitate decomposition of silver cyanides and separation of silver, by adding a proper amount of a water-soluble metal hydroxide to a liquid containing a dicyanoargentate of AgCN, and then heat-treating the liquid at a given temperature.
CONSTITUTION: One or more LiOH, NaOH, KOH, Ca(OH)2, Ba(OH)2 and Sr(OH)2 is added to a liquid containing a dicyanoargentate [Ag(I)] shown by a general formula of M[Ag(CN)2]n or AgCN at a rate of 0.05mol per 1g atom of silver. Thereafter, the mixed solution is heat-treated at a temperature of at lowest 165°C.
