The most effective way to recover fine placer and free mill gold is to classify, classify, classify. Our 4 set, fine mesh, classifiers will do just that.
Each classifier is stackable and fits over a 5 gallon bucket. Simply take your concentrates and wash them through the stack with a garden hose. After rinsing the material through the classifiers, you will end up with 4 classifications (1/30", 1/50", 1/70" & 1/100").
When you're ready to pan, you will begin working your 30 mesh first, followed by the 50, 70 & 100 mesh material. You can also use the classified material in your Blue Bowl or Miller Table for maximum recovery.
