It's Elemental The Element Aluminum
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.
Almatis :: Our History
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
Aluminium Mining And Processing Mining
2021-7-15 Aluminium is basically obtained by using a technique called the Bayer’s process developed by Karl Joseph Bayer, an Austrian chemist in 1888. Since bauxite is an aluminium ore, aluminum is thus produced by separating aluminium oxide from iron

The History of Aluminum Foil: Just don't Call it Tin Foil
2020-9-11 In 1889, Carl Joseph Bayer, a chemist from Austria, managed to extract alumina from an alkaline solution known as aluminum oxide. This process is known as the Bayer process, and it remains the technique used in the production of nearly 90 percent of all aluminum around the world. The Price of Aluminum from the 1840s 1900s

The history of aluminium industry
Karl Joseph Bayer, an Austrian chemist, invented a cheap and feasible alumina (aluminium oxide) production method in 1889 when working in St. Petersburg (Russia) at the Tentelevsky production facility. Going forward, Alumina became the basic raw material for aluminium production.
Who Discovered Aluminum? Who Discovered It
Austrian chemist Karl Joseph Bayer should also be counted among the many geniuses who discovered aluminum. It was in 1888 that Bayer formulated an inexpensive means of extracting aluminum from bauxite, an ore containing a number of compounds as well

The aluminium industry: A review on state-of-the-art
2020-2-1 The Bayer process is the most commonly used refinement route, though certain countries use alternatives called the combined or parallel Bayer-Sinter process and the Nepheline-based process [20,37]. This section describes purely the Bayer Process. Due to the impurities in the bauxite ore, it requires treatment to produce purer alumina, Al 2 O 3.

2019-9-9 In 1889, Austrian chemist Carl Joseph Bayer discovered a method of purifying bauxite (aluminium’s most common ore) to yield alumina. The Bayer and Hall-Héroult processes remain the basis of aluminium production to this day. As for the name, ‘aluminium’ was adopted in the early 19th century because the -ium suffix sounded ‘classical’.
