river gold mining techniques
An Introduction to Placer Gold Mining
Aug 14, 2019The most basic kind of gold placer mining is the using a prospector's pan to swirl sediment-filled water so that unwanted sediment spills out to leave bits of gold behind. This method is based on the fact that gold is heavier than typical sediment. This concept is the foundation for all placer mining techniques.

The American History of Gold Mining
With this method, gold miners used metal pans to scoop up material from river beds. After swishing the sand, stones and dirt around, if there were gold pieces in the pan, they would settle to the bottom because of their weight. When it came to looking for gold, the method used also depended upon where the search was taking place.
