Precious metals occurring as fission products. Ruthenium and rhodium are precious metals produced as a small percentage of the fission products from the nuclear fission of uranium. The longest half-lives of the radioisotopes of these elements generated by nuclear fission are 373.59 days for ruthenium and 45 days for rhodium [clarification needed].
Gold extraction. Cyanide leaching "heap" at a gold mining operation near Elko, Nevada. On top of the large mounds of ore, are sprinklers dispensing a solution of cyanide. Gold extraction is the extraction of gold from dilute ores using a combination of chemical processes. Gold mining produces about 3600 tons annually, [1] and another 300 tons ...
Nuclear transmutation is the conversion of one chemical element or an isotope into another chemical element. [ 1] Nuclear transmutation occurs in any process where the number of protons or neutrons in the nucleus of an atom is changed. A transmutation can be achieved either by nuclear reactions (in which an outside particle reacts with a ...

Linux (/ ˈ l ɪ n ʊ k s /, LIN-uuks) [11] is a generic name for a family of open-source Unix-like operating systems based on the Linux kernel, [12] an operating system kernel first released on September 17, 1991, by Linus Torvalds.
Gold can be drawn into a monatomic wire, and then stretched more before it breaks. [14] A gold nugget of 5 mm (0.20 in) in size can be hammered into a gold foil of about 0.5 m 2 (5.4 sq ft) in area. Gold is the most malleable of all metals. It can be drawn into a wire of single-atom width, and then stretched considerably before it breaks. [14]
