· Gold leaching by organic base polythionates: new nontoxic. The proposed method of the gold recovery comprises leaching with a solution of a mixture of sodium and ammonium hydrosulfite and thiosulfate, by sorption of the thiosulfategold complex on a highly basic anion exchanger and by isolation of the highly basic anion exchanger, the sorption being carried out 210 hours after the leaching.

· Sodium thiosulfate is used in water purifiion plants for town water. Don't worry about it. The silver in it will become silver sulfide (no shortage of available sulfur compounds in the sewer!) which is stable and won't bother any living thing (so stable that sulfided prints last longest). Recover the silver if it's convenient, of course.
