Extractive metallurgy is the art of extracting metals from their ores and refining them. This book deals with the processes, operations, technologies and processing routes of extractive metallurgy, i.e. the (production) extraction of metals from ores, concentrates (enriched ores), scraps and other sources and their refining to liquid

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, …

express the proportion of gold contained: 24 carats are pure gold, 18 carats are 75% gold, and so on. Gold forms alloys with a number of metals (see Table 2-2). Mercury wets gold particles, forming amalgams, and it is used in gold extraction operations to selectively remove gold from ground ores. Gold has a very low solubility (0.13%) in mercury.
