    Metallurgical assay - Wikipedia

    A metallurgical assay is a compositional analysis of an ore, metal, or alloy.. Some assay methods are suitable for raw materials; others are more appropriate for finished goods. Raw precious metals are assayed by an assay off.Silver is assayed by titration, gold by cupellation and platinum by inductively coupled plasma optical emission spectrometry (ICP OES).
