Nitrate leaching is head operation in affining of high silver content products of copper electrolysis, lead, jewellery manufactures, and also a radio-electronic breakage. The thermodynamics of silver opening processes in nitric acid solutions with participation of oxidizers and without those is analyzed in the present article. The received results have been checked up during laboratory experiments on dissolution of an silver containing waste of the jewellery industry.
