zinc metal shavings. Gold and silver would precipitate out of solution by a simple replacement reaction procedure. Around 1920, zinc shaving precipitation was replaced by the Merrill-Crowe method of zinc precipitation. The Merrill-Crowe process starts with the filtration of pregnant solution in media filters. Filter types used include pressure leaf filters, filter presses, and vacuum leaf

18.04.2016The gold is then removed from the solution by precipitation with zinc dust. Dust is used instead of the zinc shavings formerly employed on account of the large surface area made available. The method is based on the fact that gold and silver are electronegative to zinc and that the following reaction occurs in the precipitation process.
