But grinding is a costly and energyintensive process. To Hart, Meroueh, and Eagar, the most promising approach — first introduced by Jonathan Slocum ScD '18 while he was working in Hart's research group — involved pretreating the solid aluminum by painting liquid metals on top and allowing them to permeate through the grain boundaries.

The aluminium production process is much more complex and requires huge amounts of electricity. For this reason, aluminium smelters are always built in the vicinity of power energy sources, usually hydroelectric power plants that don't contaminate the environment. But let's start at the beginning. Bauxite Mining. Alumina Production.
