>I am looking for information on means of recovering silver from a silver
>plating bath. The challenge in finding a means of recovery is the small
>volume generated by the facility. They only generate between 12 & 15
>gallons of spent bath annually at a rate of about a gallon a month. The
>initial bath composition is 168 grams of potassium cyanide, 89.7 grams of
>silver cyanide, and 134.4 grams of potassium carbonate all added to 3000
>ml of DI water.
>Any thoughts are well appreciated.
