Boffins turned off by silicon switch to TILTING MAGNETS Solid state memory is already a viable technology at a decent scale, but it's hard to make it small enough to replace hard drives. However, researchers at the University of California Berkeley are taking a different angle: they would like to shrink high density storage to a size that puts it onto ICs. Their aim is twofold: to …
Worstall will be delighted to tell you though, as he has stated in his articles:
Tantalum is also produced in Thailand and Malaysia as a by-product of the tin mining there.
During gravitational separation of the ores from placer deposits, not only is Cassiterite (SnO2) found, but a small percentage of tantalite also included. The slag from the tin smelters then contains economically useful amounts of tantalum, which is leached from the slag. Future sources of supply of tantalum, in order of estimated size, are being explored in Saudi Arabia, Egypt, Greenland, China, Mozambique, Canada, Australia, the United States, Finland, and Brazil.
