Aqua Regia Digestion
Aqua Regia uses a 3:1 mixture of hydrochloric and nitric acids which act as an oxidizing agent to dissolve most oxide, sulfide and carbonate minerals and is an excellent trace level exploration tool.
Four-Acid or ‘near total’ digestion uses a combination of hydrochloric, nitric, perchloric and hydrofluoric acids. Only the most highly resistant minerals will not be dissolved using this type of digestion.
