Placer mining
- A group of mining techniques known as placer mining make use of water to remove valuable minerals from the surrounding dirt.
- The first placer deposits were literally just flecks of gold in a slurry of sediment that could be retrieved by expert miners using only a dinner plate-sized pan and river water.
- In comparison to lode mining ore, small placers are also more simple to mine, and the ore often requires less processing.
- Gold's high density leads it to descend from running water more quickly than the lighter siliceous elements with which it is found, and placer mining takes use of this fact.
- Although the fundamentals of placer mining have not changed since its inception, techniques have significantly advanced.
