Abstract

Invenţia se referă la un procedeu de obţinere a aurului şi argintului. Procedeul conform invenţiei constă din solubilizarea unor concentrate piritoase refractare, în soluţii amoniacale de tiosulfat de sodiu, în prezenţă de catalizator de cupru bivalent; suspensia obţinută se filtrează, după care urmează o electroliză în mediu alcalin, din care rezultă aur, argint şi cupru, care se separă prin solubilizare într-o soluţie de acid sulfuric.
