How to Separate Silver & Gold by Cementation

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

Gold & Silver Confiscation: Can the Government Seize

Storing gold and silver where a government is less likely to be able to reach it quickly and easily is smart buffer to put in place. First, as many have noted before, keeping it outside the banking system is a good step. Many references cite how banks have been known to hypothecate gold, i.e. lend it out to someone other than its rightful owner, putting it at systemic risk. Just as importantly, during the modern “bail-ins”
