Hydraulic Gold Mining

But hydraulic mining was still widely used in placer gold mines on Alaska in the early 20 th century. Today, hydraulic gold mining is only rarely practiced on an industrial scale, but gold mines on Alaska sometimes use it. It survives mostly in artisanal form in remote, undeveloped and largely unregulated areas of the world.
