In contrast to lode deposits, placer deposits are much more accessible and require less specialized equipment and knowledge to mine. Placer deposits are created when gold is eroded from its original lode deposit and concentrated by the forces of water, wind, or gravity. Placer deposits can be found in streambeds, river channels, and other …

The rivers flow over gravel, washed, separating and concentrating alluvial gold and heavy metals into specific layers. While mining gold is commonly exploited by mining using explosives and "cyanation," alluvial gold is exploited through gravitational washing and gravity sorting with mechanical, ecological equipment.

Conventional hard rock mining can be considered profitable from about 1 g of gold per tonne of rock, but mining alluvial gold can be economical from as little as 0.3 g per cubic metres of gravel. Alluvial gold deposits can contain substantially high gold grades. When most people think about gold mining, two images come to mind.
