Изобретение относится к гидрометаллургии благородных металлов, в частности, к извлечению золота и серебра из упорных руд и концентратов. Способ включает предварительное сернокислотное растворение примесей и последующее выщелачивание золота и серебра кислым раствором тиокарбамида в присутствии феррисульфита и тиоцианата.The invention relates to hydrometallurgy of precious metals, in particular, to the extraction of gold and silver from refractory ores and concentrates. The method involves preliminary sulfuric acid dissolution of impurities and subsequent leaching of gold and silver with an acidic solution of thiocarbamide in the presence of ferrisulfite and thiocyanate.
