Dry blowing is a method to extract gold particles from dry soil without the use of water. It is a form of winnowing.

Methods

  • One method is to pour dry soil from a height into a pan, allowing the wind to blow away finer dust. The denser gold particles to fall into the pan.
  • Alternatively, the prospector would use one pan and throw dirt up into the air and catch it.
