Column chromatography - Wikipedia

Column chromatography in chemistry is a chromatography method used to isolate a single chemical compound from a mixture. Chromatography is able to separate substances based on differential adsorption of compounds to the adsorbent; compounds move through the column at different rates, allowing them to be separated into fractions.

Separation processes are an important part of the aluminum manufacturing process. The three basic processes used in making aluminum are the Bayer process, for the conversion of bauxite into alumina, the Hall-Heroult process, for the electrolytic smelting of alumina to aluminum, and the alloying, casting, forging, and fabrication processes for making products.

Bayer process - Wikipedia

The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer. Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica…
