Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is generally limited to rich ores. El Teniente, in Chile, is the world's largest underground copper mine. Open pit mining is employed when the orebodies are extensive, low in grade, and ...

the ore is done on site, the tailings generated also have to be managed. Ores with a low metal content, say, less than %, generate significant quantities of tailings. In certain mines where ores have high sulfur content, drainage from mine workings and waste heaps can become highly acidic and can contain high concentrations of dissolved heavy metals. This acid mine drainage (AMD) can have ...

Types of Exploiting. Exploiting (abusing ingame features or bugs to gain an advantage) is the most common form of cheating. This can include using another program to exploit flawed features/bugs. Abusing Codes. This involves using alternate accounts to redeem codes, then trading the rewards from those codes to the player's main account. In an attempt to prevent this, the developers have added ...

Leaching is done from piles of poor ore (compact leaching) or directly from the ore (if it is porous or cracked). In order to create a sufficient number of cracks in the ore, it is loosened by explosions using ordinary explosives or atomic charges (underground leaching). In these cases the solutions are supplied to the ore from above; the enriched solutions (which have soaked through the ore ...
