2 天前· Aluminum, or aluminium (Al), is a silvery white metal with a melting point of 660 °C (1,220 °F) and a density of 2.7 grams per cubic cm. The most abundant metallic element, it constitutes 8.1 percent of Earth ’s crust. In nature it occurs chemically combined with oxygen and other elements.
2004/10/01· Known reserves of bauxite the main raw material used in the production of aluminium metal are currently estimated to be more than 40-billion tons, which will, in turn, last for more than
The production of primary aluminum metal begins with bauxite ore, which is composed of hydrated aluminum oxide (40% to 60%) mixed with silica and iron oxide. It takes approximately 4 to 5 tonnes of bauxite ore to produce 2 tonnes of alumina. In turn, it takes approximately 2 tonnes of alumina to produce 1 tonne of aluminum.
2018/09/11· Aluminium smelting costs are expected to continue to rise in 2018 and 2019, as raw materials ps remain elevated, but margins will decline. CRU’s Alumina P Index (API) averaged $353.95/t in 2017, up over $100/t compared to 2016 and the highest annual average since 2011.
Main article: Bauxite mining in the United States The principal raw materials for aluminum production are bauxite (for primary production) and scrap (for secondary production). Primary aluminum production consumes a great deal of electricity, which makes up about a third of the cost.
