Coal Mining and Processing Energy Trends Insider
Mining the Coal. Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. Many U.S. coal beds are very near the ground''s surface, and about twothirds of coal production comes from surface mines. Modern mining methods allow us to easily reach most of our coal reserves.

Aluminium recycling Wikipedia
Aluminium recycling is the process by which scrap aluminium can be reused in products after its initial production. The process involves simply remelting the metal, which is far less expensive and energyintensive than creating new aluminium through the electrolysis of aluminium oxide (Al 2 O 3), which must first be mined from bauxite ore and then refined using the Bayer process.
