Extraction of Gold

When the gold has solidified, the molten silver chloride collected on the surface is run off, carrying with it a small proportion of gold. When silver is the chief impurity in the gold, as in that found in Australia, the process is specially applicable. The gold has a degree of purity of 99.1 to 99.7 per cent.
