One essential stage in the process was the extraction of alumina (Al2O3) from the ore bauxite, and an efficient method to do this was developed by Karl Joseph Bayer in 1888. A further essential factor was the availability since the early 1870s of generators capable of supplying electricity on the large scales required for electrolysis.

Karl Joseph Bayer, an Austrian chemist, developed this process in 1888. The Hall-Héroult and Bayer processes are still used today to produce nearly all of the world's aluminum. With an easy way to extract aluminum from aluminum oxide and an easy way to extract large amounts of aluminum oxide from bauxite, the era of inexpensive aluminum had begun.

The promising demand for large quantities of pure alumina to produce aluminum metal inspired Dr. Karl Joseph Bayer to develop a low-cost method for extracting alumina from bauxite. The 1887 invention of the Bayer process, the principal industrial means of refining bauxite to produce high-purity alumina at relatively low costs, can be seen as ...
