Geoscience Lab, (OGS) MRD123 Lithogeochemical Database: silver FA ICP-AES

General Methodology:

Platinum, palladium and gold values were determined by silver fire-assay ICP-AES. The precious metals were concentrated into a silver bead by the classical fire-assay method; the silver bead was dissolved in nitric acid; the silver was precipitated; Pt, Pd, and Au were dissolved in aqua regia; and the solution was analysed by ICP-AES.
