Austrian chemist Carl Josef Bayer found out a method of purifying bauxite to produce alumina in 1888 in a textile manufacturing unit in Saint Petersburg and was issued a patent later that year;[94] This is certainly now often called the Bayer procedure. Bayer sintered bauxite with alkali and leached it with water; right after stirring the solution and introducing a seeding agent to it, he observed a precipitate of pure aluminium hydroxide, which decomposed to alumina on heating.
