Dry blowing is a method to extract gold particles from dry soil without the use of water. A machine specialized to use this method is known as a dry blower. It is a form of winnowing.
Methods
[edit]- 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.[1]
- Alternatively, the prospector would use one pan and throw dirt up into the air and catch it.[2]
