U.N. Kills Any Plans to Use Mercury as a Rocket Propellant

Cars That Think

A recent United Nations provision has banned the use of mercury in spacecraft propellant. Although no private company has actually used mercury propellant in a launched spacecraft, the possibility was alarming enough—and the dangers extreme enough—that the ban was enacted just a few years after one U.S.-based Mercury is a neurotoxin.

Rio Tinto commissions bauxite residue filter presses at alumina refinery in Québec; 17 minutes vs. 3 years

Green Car Congress

Like most ores and soils, bauxite can contain trace quantities of metals such as arsenic, beryllium, cadmium, chromium, lead, manganese, mercury, nickel and naturally-occurring radioactive materials, such as thorium and uranium. Industrial filtration consists in applying a mechanical pressure to dry bauxite residue, making it easier to store.
