Dec 11, · The new g rush has begun. Mining targets The Moon. Many refining and manufacturing techniques in metal processing rely on gravity. The Moons gravity is only a sixth of ours but its enough to create a stable operations base close to Earth. Resources Helium3, g, platinum group metals, rare earth metals, water. NearEarth asteroids

The mining techniques used in the G Rush evolved over time. This evolution tells a much more complex story than it seems at first glance; the change in mining techniques reveals the myth of the G Rush. In legend, the G Rush was where a poor farmer from New York or Pennsylvania could go, "strike it rich", and return home a wealthy man.

Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of g. Partially due to cyanide, modern mines are. much larger than before cyanide was used; create vast open pits; and; produce huge quantities of waste. More than 20 tons of mine waste are generated to produce enough g for a typical ring.

There are four main mining methods underground, open surface (pit), placer, and insitu mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other

When surface deposits of g declined, placer mining and the settlements built for this purpose were abandoned. If the harder to access deposits of g were to be extracted, a new, more effective method would have to be implemented. The Transition to Hydraulic Mining . The advent of the . Industrial Revolution
