Amalgam (chemistry) term pollution. Today, mercury amalgamation has been replaced by other methods to recuperate gold and silver from ore in developed nations. Hazards of mercurial toxic waste have played a major role in the phasing out of the mercury amalgamation processes. However mercury amalgamation is still regularly used by small-scale gold placer miners (often illegally) & particularly in developing countries.

The presence of these salts in water can be detected with a probe that uses the readiness of mercury ions to form an amalgam
