Fine Gold Recovery With a Blue Bowl Concentrator
Oat gold, fine gold, micron gold (micros), and gold dust are all terms used for the smallest forms of gold. These minute particles get lodged under rocks and pebbles and collect on the top of bedrock. They originate from lode gold upstream that breaks apart and is washed downhill. The farther the gold tumbles, the smaller the fragments get.
