How Mercury & Gold Amalgamation Works
The reason for this is that coarse gold, being easily amalgamable, is almost all caught on the inside plates, while fine gold, even if amalgamated; in the battery, forms a more fluid amalgam which passes through the screens and is caught outside. Coarse gold forms a richer and stiffer amalgam than fine gold, for the reason already given on p. 15.
