SUMMARY

The discussion focuses on the extraction of grain-sized gold from dirt, emphasizing the importance of density in the process. Participants recommend creating a slurry by mixing the ore with water, allowing the gold to sink due to its high specific gravity. They highlight that true gold does not glitter like pyrite and suggest using density tests to differentiate between the two. Techniques such as gold panning and careful agitation of the pan are also discussed as effective methods for separating gold from other materials.

PREREQUISITES
  • Understanding of specific gravity and density principles
  • Familiarity with gold panning techniques
  • Knowledge of distinguishing characteristics between gold and pyrite
  • Basic skills in creating a slurry for mineral separation
NEXT STEPS
  • Research advanced gold panning techniques and tools
  • Learn about specific gravity testing methods for minerals
  • Explore the geology of placer gold deposits
  • Investigate methods for separating fine gold from black sand
USEFUL FOR

This discussion is beneficial for amateur gold prospectors, hobbyists interested in mineral extraction, and anyone looking to improve their gold panning skills.

Actually, it is smaller. Is is more like glitter-sized. What process do I use to extract it?
 
Chemistry news on Phys.org
Due to gold's density (specific gravity) you can place your ore in water and mix it well. Turn it into a slurry. All the gold will sink to the bottom.

Check out some online videos on gold panning. Even lead weights and bullets will roll around in a pan of water. The gold sticks like it is nailed there.

If you see 'glittery' stuff, it is probably pyrite, not gold. Gold really doesn't doesn't glitter.

Right. More like a warm yellow glow. I love panning for gold and it's always fun to see that glow in the dregs as you slosh out the lighter stuff.
 
Yeah, the glitter-like gold doesn't sink favorably either. Are you stating that even glitter-size gold sinks? Is there any other kind of test I can run on it?
 
IF it's gold, it should sink, as buoyancy is a function of density and gold is very dense, no matter the size of the particles.

Density is the best test. Even gold dust sinks. We have a river locally that contains some placer gold, and when you agitate the pan, the regular sand and dirt wash out cleanly, leaving a reddish "sand" composed of weathered garnet, which also washes out, leaving a fine dense black material, AND (if you are lucky or skillful) gold. If you are paranoid about losing even a fine particle of gold, you can take all the black material home for more careful separation, but I just dip more water, agitate, and swirl and let density do the trick.
 
Thanks guys. Unfortunately, it appears to be pyrite like Shootist suggested - fool's gold.
