How to Separate Precious Metal DoItYourself

2011-4-13  The gold should slip down into the smelting vessel. After this occurs, you can cool and remove the gold from the smelting vessel and also remove the slag as well. It's common at this point to refine the gold through a separate refinement process to ensure a high level of purity.

Fine Gold Recovery. Separating Placer Gold Particles from ...

Recovering fine gold from black sands is one of the most challenging aspects of gold mining. While we are all hoping to find that once-in-a-lifetime gold nugget, the vast majority of gold that we find as prospectors is very small in size, ranging from gold flakes down to dust so small that it is nearly invisible. Extremely fine particles of gold like this can be very difficult to separate
