    Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted. Placer deposits are composed of relatively loose material that makes tunneling difficult and so most means of extracting it involve the use of water or dredging.

    Mar 06 2017 · Hard rock mining followed veins of gold to get at the source. Hydraulic mining took the opposite course focusing on scale to process enough gravel to extract what small trace amounts of gold still remained in placer deposits. 11 million ounces of gold are estimated to have been extracted via hydraulic mining by the mid-1880s.
