What Were Some of the Tools That Were Used in the Gold ...

 · 5 Pans. Panning for gold was also known as "placer mining." Early miners sat by riverbeds, scooping wet soil into shallow metal pans. They swirled the pans, washing away the dirt to hopefully discover particles of gold. Though more complex equipment was eventually invented, pans were still a useful tool to distinguish gold from dirt.
