At just one time, The extraction of pure aluminum metallic from aluminum oxide was very difficult. The initial course of action demands that aluminum oxide initial be melted, then electrolyzed. This is difficult and expensive because aluminum oxide melts at only pretty large temperatures. An affordable approach for carrying out this operation was uncovered in 1886 by Charles Martin Hall, at some time, a university student at Oberlin Faculty in Ohio.
