hydraulic closed loop gold mining

Mar 06, 2017· 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.

If someone talks about an “openloop” or “closed loop”hydraulicsystem, what exactly do they mean?Fundamentally, the difference can be described in just two sentences, and is most easily defined by the pump: An openlooppump draws all of its flow directly from a reservoir and sends the majority of it directly back to the reservoir after performing its function.

Buthydraulic miningwas still widely used in placergoldmines on Alaska in the early 20 th century. Today,hydraulic gold miningis only rarely practiced on an industrial scale, butgoldmines on Alaska sometimes use it. It survives mostly in artisanal form in remote, undeveloped and largely unregulated areas of the world. Read More

Aclosed loopcircuit can operate smoothly in forward and reverse directions without a directional valve being involved. This eliminates the need for the valve component, which can be costly and take up valuable real estate on mobile equipment. This also cuts down on hose and fitting complexity and space. Theclosed looppump is usually a ...
