He went to Paris for study at the School of Mines.
While a student at the École des Mines, Heroult began working on the electrolysis of aluminum compounds. Early in 1886 he invented an electrolytic process for the production of aluminum from bauxite.
It was announced just three months after the American chemist Charles Martin Hall had filed original patents on an identical process; both inventors were 22 years old. Their process was one of the first commercial uses to which the electric furnace was put, and it reduced the cost of aluminum from $8 a pound to 53 cents.
