Mining, process of extracting useful minerals from the surface of the Earth, including the seas. A mineral, with a few exceptions, is an inorganic substance occurring in nature that has a definite chemical composition and distinctive physical properties or molecular structure.
An Introduction to Placer Gold Mining
The 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.
