What is alluvial mining?

Alluvial mining is a type of mining that involves the extraction of minerals or precious metals from sediment, such as sand, gravel, or silt, that has been deposited by flowing water. This type of mining is typically done in rivers, streams, or floodplains where the current has deposited valuable minerals or metals over time. Alluvial mining is often done using simple techniques such as panning or sluicing, and can be a more environmentally friendly method of mining compared to other forms of mining that involve more extensive excavation and processing.
