The process of claim 1 wherein an emulsifying agent capable of coating freshly formed gold particles and preventing coalescence thereof is mixed with the aqua regia solution of gold prior to adding the reducing agent thereto in an amount sufficient to precipitate said metallic gold as a fine powder.
#0183;#32;Another way of precipitating gold is with iron shavings or zinc dust. The iron or zinc does into solution and the gold coats the zinc or reports as a brown powder which is easy to melt into a globule of gold using an oxyacetylene flame. There was a small gold mine in Zimbabwe where gold was collected by ordinary dish scrubbing iron wool.

This true refine process is much lower volumes of liquid so diluting it three times to get the AgCl to precipitate out doesn''t involve large During pouring of salt on aqua regia, white powder will appear and soon will be settle under, that white power is silver collect them. Then cook it. Best
