A Poor Man's Method of Smelting Gold Sciencing

2018-5-22  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

Pocket knives, paper clips, and iron nails generally have a hardness of 5.5-6.5. Glass can be scratched by any mineral harder than ~5.5. A US copper penny has a hardness of 3.0 and human fingernails have a hardness of ~2.5. By using these common objects you can determine the relative hardness of your mineral specimen with some degree of accuracy.

Gold Volcanoes - Using Geology to Find Gold Deposits

This is why gold is so often found associated with quartz. Since the water which contains dissolved gold must follow these fractures up through the bedrock, quartz can be found in nearby concentrations. These become gold veins or lodes. These veins are where hard rock gold mines follow and remove the gold
