Sep 29, 2017018332Panning for gold was also known as quotplacer mining.quot 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.

There are four main mining methods underground, open surface pit, placer, and insitu mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
