Pantherlikher said:Following along intently. Have either one of you tried dissolving some in nitric acid and seeing if any silver drops using copper?
This would help confirm silver.
Grinding glass to a powder will be difficult for most as shards of glass are as dangerous as acids we use. So before diving into the deep end and make a grinding/ processing station for glass; it would be nice to find out if it is worth the effort.
Keep us informed please.
I watched an interesting you tube video recently about lye dissolving glass. Could something like this help with recovering the silver?skyos said:For the external glass , it s stay on the glass, for the internal glass , i m not sure if it s stay inside the white film or just under...
Hey guys, any one knows anything about this process?
"The method of extraction of silver from scrap of plasma TV monitors using noncyanide reagents – sodium thiosulfate and acidothiourea – was investigated, which was followed by silver recovery from acidothiourea leach solutions. It was found that acidothiourea solution gave almost complete extraction of silver while thiosulfate provided only 40% extraction. The rate of silver extraction using acidothiourea solution was found to be extremely fast. An increased dissolution rate was also found at elevated temperature. The recovery of silver through coagulation-precipitation from acidothiourea leach solutions was carried out with a natural biodegradable material, persimmon tannin extract. It was proved to be a promising material for complete silver recovery. Besides, precipitative recovery of silver by means of cementation with zinc powder was conducted. It was found that simple cementation with zinc powder exhibits a very good precipitative property for which it could be used in hydrometallurgical processing."
