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, …
