Re: People are a Big Problem in Mining
The reason the new Pilbara operation is practical is that they built an almost totally robotic mine, operated form 1500km away, even the trains to haul it to the coast are automated.
Instead of moving the ore to the smelters, the next step is to simply move the smelters to the ore. If the smelter is also automated it makes more sense for it to be in the middle of Australia than in the middle of Sheffield. It's obviously cheaper to move 1ton of finished iron or steel than 5tons of ore or 20tons of rock. Then you move the automated factories to be next to the steel works.
It makes a lot more economic and environmental sense to have a train appearing out of the middle of the outback bearing Holdens than crushed rock.
