Popis:	The paper presents the main thermodynamic aspects related to the gold dissolution with thiosulphate, thiourea and thiocyanate. The thermodynamic stability of the gold complexes and the reaction mechanisms that ensure the gold dissolution in the most representative lixiviants with potential for use in the gold industry are analyzed. The performances of the lixiviants are analyzed in several ways in antithesis with those of the cyanide: ecological, technological and economic.
