To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravellike material then enters rotating drums filled with steel balls.
The mills he designed and built, first the pulp mill, then the paper mill, together served as a transformer, turning a prolific raw material into an industrial product, using water power from the river to fuel the process at every turn. This process transformed the landscape as well, as the iron industry had before it.
