The Environmental Impact of Aluminum (And Why it's Still ...
Aluminum (or Aluminium, if you're not from the US) is an abundant element within Earth's surface— but getting it out of the ground is an arduous process, requiring heavy machinery to plow up acres and acres of land. Fortunately, the environmental impact of that process can be somewhat balanced out by postmining rehabilitation, efficient recycling, and generally reducing our consumption.
Mining and Refining – Process
Mining and Refining – Process. The Bayer Process was invented and patented in 1887 by Austrian scientist Karl Josef Bayer.
