Graphite flakes can cost around US$0.9/kg carbon. [20] Price of synthetic industrial diamond for grinding and polishing can range from 1200 to 13 300 USD/kg, while cost per weight of large synthetic diamonds for industrial applications can be on the order of million dollars per kilogram. [21] 7: N: Nitrogen: 0.0012506: 19 (5.263 × 10 17 kg) 0. ...

Despite carbon's resistivity against corrosion, it is still consumed at a rate of 0.4–0.5 kg per each kilogram of produced aluminium. Cathodes are made of anthracite; high purity for them is not required because impurities leach only very slowly. The cathode is consumed at a rate of 0.02–0.04 kg per each kilogram of produced aluminium.
That year, aluminium was put to the market at a price of 300 F per kilogram. [54] At the next fair in Paris in 1867, visitors were presented with aluminium wire and foil as well a new alloy—aluminium bronze, notable for its low cost of production, high resistance to corrosion, and desirable mechanical properties. [55]
The contracts prices are quoted in US dollars per tonne. LME prices have minimum tick sizes of $0.50 per tonne (or $12.50 for one contract) for open outcry trading in the LME Ring and electronic trading on LMEselect, while minimum tick sizes are reduced for inter-office telephone trading to $0.01 per tonne (or $0.50 for one contract).
Because of the low availability relative to demand, rhenium is among the most expensive industrial metals, with an average price exceeding US$6,000 per kilogram, as of mid-2009. It first traded in 1928 at US$10,000 per kilogram of metal, but traded at US$250 per Troy ounce in mid-2010. [82] It traded in July 2010, at about US$4,000–4,500/kg. [83]
The Hall–Héroult process is the major industrial process for smelting aluminium. It involves dissolving aluminium oxide (alumina) (obtained most often from bauxite, aluminium 's chief ore, through the Bayer process) in molten cryolite and electrolyzing the molten salt bath, typically in a purpose-built cell. The Hall–Héroult process ...
Making a ton of primary aluminum consumes at least 12,500 kW-hr, and most plants consume 14,500 to 15,000 kW-hr per ton of primary aluminum. [17] Secondary production of a given unit of aluminum requires about 10% of the electricity of primary production. The United States mined production of bauxite for primary aluminum production is ...
