ANNOTATION:
The studies performed resulted in the development of a method enabling silver recovery from radioactively contaminated silver-containing products. This method includes the following stages: preliminary decontamination of products, dissolution of silver product fragments in a nitric acid solution, production of finely dispersed silver by displacement of silver metal with copper, submerged melting of finely dispersed silver at a temperature of at least 960 °. To reduce the operating costs, evaluated was the feasibility of silver recovery from its compounds (chloride, sulphate and oxide).
 
Keywords: radioactive waste, decontamination, silver, radioactive contamination, precipitation, silver recovery, niello, remelting, bars.
