Aluminum processing - Ores | Britannica
Only earth with an aluminum oxide content of 30 percent or more is considered practical. Only those ores containing significant concentrations of the minerals gibbsite and boehmite, which contain 65 and 85 percent alumina, respectively, are generally considered economical to be processed.

Copper Ore Processing Methods
The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger ...
List of Important Metals and their Ores - Jagranjosh.com
Ores are those minerals from which metals are extracted commercially and economically. Like Bauxite (Al 2O 32H 2O) is the ore of Aluminium which contains 50% to 70% of Aluminium Oxide. Elements of Metals can be broken down into several categories; one of them is transition metals.
ore | National Geographic Society
Aluminum, for example, is usually found in the ore called bauxite. Aluminum found in bauxite is used in containers, cosmetics, and medicines. Smelting and Electrolysis . When miners find rock containing mineral ore, they first extract the rock from the earth. This can be a huge process, sometimes displacing millions of tons of dirt. The rock is then crushed by powerful machinery.
Mining and Refining – Process - World Aluminium
Conditions within the digester (caustic concentration, temperature and pressure) are set according to the properties of the bauxite ore. Ores with a high gibbsite content can be processed at 140°C, while böhmitic bauxites require temperatures between 200 and 280°C.
Wills Mineral Processing Technology | ScienceDirect
Mineral processing—sometimes called ore dressing, mineral dressing, or milling—follows mining, and it prepares the ore for extraction of the valuable metal in the case of metallic ores and produces a commercial end product from products such as iron ore and coal.
