Coltan - Wikipedia
Coltan (short for columbite–tantalites and known industrially as tantalite) is a dull black metallic ore from which the elements niobium and tantalum are extracted. The niobium-dominant mineral in coltan is columbite (after niobium's original American name columbium), and the tantalum-dominant mineral is the tantalite.. Tantalum from coltan is used to manufacture tantalum
Cell Phone Recycling | Louisville | ECO-CELL
Tantalum, is used in cell phones to coat capacitors which makes the devices very energy efficient. Tungsten is the material that is used to make a cell phone vibrate. Solid state electronic devices use very low voltages and currents which are easily interrupted by corrosion or tarnish at the contact points.
Tantalum - Element information, properties and uses,
Tantalum is relatively rare: it's the fiftieth commonest element in the earth's crust. There are only 40 miligrams of the stuff in a cell phone, but with there currently being about two phones for every three people on Earth, that's still a lot of tantalum.
Tantalum pentoxide - Wikipedia
These are used in automotive electronics, cell phones, and pagers, electronic circuitry; thin-film components; and high-speed tools. In the 1990s, interest grew in the use of tantalum oxide as a high-k dielectric for DRAM capacitor applications. It is used in on-chip metal-insulator-metal capacitors for high frequency CMOS integrated circuits.
