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 …

Migrating Gold: If gold starts moving down the table, this usually means your water flow is too fast or your table angle is too steep. Adjust accordingly. No Gold: If you see no gold, consider increasing the water flow slightly or adjusting your angle. If you still don't see gold, you may need to re-check your material preparation steps.

Riffles separate heavy and light particles. Gold recovery with sluices can vary depending on several factors. Fine gold losses can be minimized by cleaning up more frequently, reducing the speed of the slurry flow to around 0.50 to 0.80 m/s., and decreasing the feed size by performing a previous screening.
