A Poor Man''s Method of Smelting Gold | Sciencing
· You can remove the most common metals found in gold ore (copper, zinc and lead) using elements that bond with oxygen at lower temperatures than gold. This oxidation process will make copper oxide, zinc oxide and lead oxide — all of which are less dense than pure gold and will float to the top of your crucible allowing the slag to be sloughed off.
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.
