Alluvial and Placer Mineral Deposits | Geology for Investors

 · Gold, particularly, has often not moved far, so a minor alluvial gold deposit can result in a major underground gold mine as in Australia''s Kalgoorlie or Bendigo gold rushes. In other places, most of the gold was in the alluvial deposits as in the Klondike/Alaska Gold Rush and the California gold rushes of the 19th century.

Alluvial Gold Mining

Alluvial Gold Mining Alluvial gold is found beneath the surface at the bottom of a creak or stream. Alluvial gold mining is the process of extracting gold from these creaks, rivers and streams and is generally considered to be the most environmentally friendly method of gold mining as a result of the reduced environmental impact when compared to underground mining.

Gold mining companies also started to use bucket dredges to mine alluvial deposits. Dredging was a large-scale means of extracting gold from extensive river-flat deposits. Dredges were like huge floating factories; operating in a pond, they excavated the gravels in front of them with large buckets, processed the gravels on-board, and dumped the treated material behind.
