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
Figure 8: Application of prestresssing bladder on a timber pack. Summary and Conclusions Roof support is a fundamental requirement for all underground mining operations. Hard rock mining operations can vary widely depending on the nature of the deposit and require varying degrees of ground support to provide a safe working environment.
Hard rock mining is the process of extracting metals and minerals encased in rocks (primary deposit). Hard rock ore can contain metals, minerals such as gold, platinum, silver, iron, copper,
This is becoming the method of choice where hard rock miners have learned the value of their tails and are using the iCON to preconcentrate the sulfides or entrapped gold. You may be able to reduce your ore to 2 to 3% and concentrate the entrapped sulfide gold. Cyanide Leaching. This is the recommended method of the Global Mercury Program.
Gold around the world is either found in hard rock deposits or as placer deposits. Hard rock, or Lode gold is still contained within ore, and various methods are used to extract the metal from the rock that surrounds it. Placer gold on the other hand occurs when natural erosion has released the gold from its host material and the gold is now a separate piece, whether that be a small speck of gold dust or a
Hard rock gold mining extracts gold in rock instead of fragments in loose sediment, producing most of the gold in the world. Openpit mining is sometimes used, for example in central Alaskas Fort Knox Mine. Barrick Gold Corporation has one of the largest openpit gold mines in North America located on its Goldstrike mine property in north eastern Nevada. Other gold mines use underground mining where

They are sometimes used just to connect different levels (winze) and sometimes to achieve greater depth than possible with just the surface shaft. You might for example drive an adit into the side of a mountain to the top of a deeply buried ore body and the sink a subshaft to access the lower levels of that ore body.
