Electroplating / Electrodeposition of Aluminum

Jan 04, 2021· Bare aluminum will passivate in air and water and oxidize further when heated, so non-conductivity is unsurprising. Electrodeposition of aluminum, Al (+3) + 3 e (-) --> Al (metal), requires an emf of -1.662 V. However, in an aqueous solution, electrolysis of water occurs at a lower emf, -1.229 V, absorbing the electrical current.

Environmental Impact of Steel - TheWorldCounts

The main ingredient in the production of steel is iron ore mined from Earth. Over 2,000 million tons of iron ore is mined mined a year - about 95 percent is used by the steel industry. Iron ore is the world's third most produced commodity by volume - after crude oil and coal - and the second most traded commodity - only beaten by crude oil.
