How Is Lead Mined?
· Once the lead ore is brought to the surface, it goes through a series of refining processes that separate out the different metals contained in the ore. For example, mines in Alaska and Missouri are zinc and lead operations. These mining operations are highly mechanized, because the work is so dangerous. The smelting operations themselves are also extremely dangerous, because lead is ...

Why the mining industry desperately needs lean thinking ...
As obvious as it may sound, the lean practice of relentlessly eliminating waste can be applied almost literally in mining: when we extract ore, the inherent value ( the metal content) is trapped in "nonvalueadding host material or rock". When we move, say, a ton of rock, there is generally a very high percentage of waste in it. Lean, supported by technology, can help us to reduce the ...
