Aluminum Extraction an overview | ScienceDirect Topics
In the electrolytic extraction of aluminium, the anodic process is the discharge (or oxidation) of the oxide ion, O 2− The net process is the decomposition of the feed alumina, Al 2 O 3, into aluminium metal and oxygen, which in turn reacts with the carbon (anode) to produce CO 2 at elevated working temperatures (eg 900 °C) The process26/08/2015· This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process Starting from either openpit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore) Having a quick look now at how porphyry ores are treated and theCopper Mining & Extraction Process Flow Chart

The extraction of copper from ore is normally carried out in three major steps The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper Thealuminum processing, preparation of the ore for use in various products Aluminum, or aluminium (Al), is a silvery white metal with a melting point of 660 °C (1,220 °F) and a density of 27 grams per cubic cm The most abundant metallic element, it constitutes 81 percent of Earth’s crust In nature it occurs chemically combined with oxygen and other elements In the purealuminum processing | History, Mining, Refining, & Facts
