Underground mining (hard rock) - Wikipedia

Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies. Soft rock mining refers to excavation of softer minerals such as salt, coal ...

Gold: The mineral native Gold information and

Gold nuggets, a popular form of Gold with collectors, are formed when erosion causes a large piece of Gold to separate from its mother rock, and then gets carried into a stream or river. The flowing water tumbles the Gold, giving it its distinct rounded shape. The Gold eventually settles at the bottom of the water, and due to its heaviness remains there. Other nuggets also get caught in the ...

Wisconsin Geological Natural History Survey » Gold

Gold is resistant to weathering, hence is often freed from the surrounding rock and redeposited as sediment. Because gold has a high density, it tends to settle out readily and be trapped with coarser sediments. Where current action is strong, lighter materials are preferentially washed away, concentrating the gold in placer deposits. In submerged gold-bearing sediments, slight shaking of the ...
