Bauxite is typically strip mined and is used to produce aluminum. According to estimates by Vietnam's Ministry of Industry and Trade, Vietnam's reserves in the Central Highlands amount to 5.4 billion tons. [2] Despite its large reserves, Vietnam produces only 30,000 tons of bauxite per year. [1]
The density of liquid aluminum is 2.3 g/ml at temperatures between 950 and 1000 °C (1750° to 1830°F). The density of the electrolyte should be less than 2.1 g/ml, so that the molten aluminum separates from the electrolyte and settles properly to the bottom of the electrolysis cell.
Production of one kilogram of aluminium requires 7 kilograms of oil energy equivalent, as compared to 1.5 kilograms for steel and 2 kilograms for plastic. [143] As of 2023, the world's largest producers of aluminium were China, Russia , India, Canada, and the United Arab Emirates , [ 141 ] while China is by far the top producer of aluminium ...

Despite the name, they are not liquid at room temperature. [1] Liquidmetal was introduced for commercial applications in 2003. [2] It is used for, among other things, golf clubs, watches, and covers of cell phones. The alloy was the result of a research program into amorphous metals carried out at Caltech.
Powdered aluminium shares many of the physical characteristics of bulk aluminium such as its molecular weight of 26.981538 g mol −1, [3] melting point of 660 °C, [4] and a boiling point of 2460 °C. [5]
Aluminum can prices vary by region and are based on weight. The average recycling value per pound of cans in the U.S. is currently $0.56. How many aluminum cans are in a pound?
Aluminum-silicon phase diagram. Aluminum forms a eutectic with silicon, which is at 577 °C, with a Si content of 12.5% [7] or 12.6%. [8] Up to 1.65% Si can be dissolved in aluminum at this temperature.
