Affinazione Oro

L'affinazione è un processo che serve a liberare l'oro da altri materiali che lo inglobano e che possono rappresentare delle impurezze nocive, cioè composti o elementi della stessa natura della lega, la cui presenza, però, non è prevista.

 Tramite la tecnica dell'affinazione dell'oro, i riifiuti della produzione vengono affinati sino a raggiungere una purezza d'oro non inferiore al 99,5%. (alcuni metodi riescono a garantire purezze maggiori del 99,9%).

Metodi affinazione oro

Ci sono vari metodi per estrarre l'oro dai materiali che lo contengono. Le differenze dei metodi sono legate alla sicurezza di attuazione, i costi, la qualità del prodotto finale, l'inquinamento ecc.

I metodi più comuni sono l'inquartazione, l'affinazione per elettrolisi, l'affinazione con cella Fizzer, la dissoluzione in acqua regia con riduzione selettiva chimica o tramite il processo Miller, meglio conosciuto come clorurazione.
