From the mining equipment used to the advancements made in mining technology, aluminum mining has progressed from primitive methods to the use of technologically advanced equipment and processes that promote a tremendous increase in aluminum production.
Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an orebody, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
What Aluminum Extraction Really Does to the Environment Aluminum takes a remarkable amount of energy to produce for consumer usage, making recycling so very important. Of all the earth's natural elements, aluminum happens to be the third most abundant resource on our planet in its raw form.
The extraction of metals from ores is what allows us to use the minerals in the ground! The ores are very different from the finished metals that we see in buildings and bridges. Ores consist of the desired metal compound and the impurities and earthly substances called Gangue.
