The history of gold begins in antiquity. Bits of gold were found in Spanish caves that were used by Paleolithic people around 40,000 B.C. Gold is the "child of Zeus," wrote the Greek poet Pindar. The Romans called the yellow metal aurum ("shining dawn"). Gold is the first element and first metal mentioned in the Bible, where it appears in more than 400 references.

Refining of gold comprises the following sequence of operations: melting, refining, de-golding, and electrorefining. Melting gold precipitates and/or gold cathodes is required for homogenization, reliable sampling, and pyrorefining. The crucible—which contains the charge—must be able to resist the chemical action of the fluxes used (mixtures of borax, niter, …
