Extract

Commercial interest in gold is persistent and resurgent, and there is a consequent need for reappraisal of its methods of analysis. Because its modes of occurrence often manifest themselves in irregular dispersion and low concentration, special care must be taken in sampling and analysis. A sufficient amount of the initial sample must be taken to ensure adequate representation, and preconcentration is often necessary to elevate the metal content to a confidence level high enough above the detection limit for the analytical technique.
