Gold Refining by Cementation with Salt at Sado in

The key technology of massive gold production was gold-silver parting by cementation process with salt. In 1996, during the excavation of the Sado Bugyōsho site, gold refining remains were found below the 1647 fire horizon. 1) A total of 29 furnaces were found. The largest furnace is an elongated shallow tray-like furnace, which resembles closely the cementation furnace illustrated in eighteenth- and

Gold Parting via Salt Cementation - Manhattan Gold

2013-6-26  In a jar, add gold/silver alloy, some burnt clay or old brick dust, salt, and just enough urine to moisten it all (trust us). Seal the jar and keep it heated, but not hot enough to melt the gold – less than 1000°C. In about 24 hours, the gold should be nearly silver-free at around 90% purity or greater.

How to Separate Silver Gold by Cementation

2016-3-24  Older processes explaining how to go about separating silver from gold by cementation were carried on practically in two ways, the first by heating gold for a long time with a mixture which evolved nitric acid on heating, and an absorbent into which any fusible salts ran; the mixture in the second method contained common salt as an essential ingredient, and some material which would assist in ...

Effect of Impurities on Gold Slimes Refining Process

2016-3-25  The gold obtained assayed 9243, and slightly over 10 per cent, was lost by volatilization. It is, therefore, inadvisable to use salt in the fuse, since gold may be transformed to a chloride and volatilised; it is also difficult to decompose the whole of the chlorine compounds unless a very large excess of sulphuric acid or nitre cake is used.
