The most obvious physical property of gold is its color. It is one of just a few minerals whose names are used frequently in common language as the name of a color. The color is not altered by tarnish or the development of an oxidized surface. However, the color of gold varies with its composition. The color of gold is not constant.
Analysis of CopperGold Ore with the Avio 220 Max ICPOES Introduction The extraction of metals from ore at a mining plant requires the routine analysis of various samples, which include the feed (crushed ore), the tails (waste ore after processing) and the concentrate (final product).
Instrumental Analysis; Fire assay is the classical technique used to determine the precious metal content of silver and or gold ore and secondary concentrates. It is more timeconsuming and elaborate than instrumental analysis, but it is generally more accurate. Fire Assay Methods. Fire assay has been used by engineers for thousands of years.
