Proper classification of material by size is the key to more efficient gold separation. This is true for roughing out your material, all the way to the final step of fine gold separation. Using a sieve works for panning, sluicing and high banking equally well.

Many of our customers use the 30, 50, and 100 mesh sieve sizes with their Blue Bowl concentrators.


Separating and processing your gold concentrates by size with a classifier makes gold recovery much more efficient and less laborious.
