What country produces the most gallium?
China produces more than 95% of the world's raw gallium, a soft, bluish metal used in making chipsets for generating high frequency radio waves in 5G base stations.
Where do you get gallium from?
Gallium is not found in its elemental form on Earth, but it is found in minerals and ores in the Earth's crust. Most gallium is produced as a byproduct of mining other metals including aluminum (bauxite) and zinc (sphalerite).
How abundant is gallium?
Gallium is a moderately abundant element in the Earth's crust. Its abundance has been estimated to be about 5 parts per million. It is found primarily in combination with zinc and aluminum ores. It is also found in germanite, an ore of copper sulfide (CuS).

How common is gallium?
Gallium has 31 known isotopes, ranging in mass number from 56 to 86. Only two isotopes are stable and occur naturally, gallium-69 and gallium-71. Gallium-69 is more abundant: it makes up about 60.1% of natural gallium, while gallium-71 makes up the remaining 39.9%.
What can I do with gallium?
Most gallium is used in electronics. It's common in semiconductors, transistors, and very small electronic devices. Gallium is able to turn electricity into light, so it's also used to make LEDs. It can also be used to make thermometers and mirrors.
Can gallium be magnetic?
Physicists have found that some liquid metals which appear to be non-magnetic -- such as mercury, aluminium, gallium and lead -- actually contain magnetic moments that appear and disappear on extremely short time scales.

Mercury is a very toxic or poisonous substance that people can be exposed to in several ways. If it is swallowed, like from a broken thermometer, it mostly passes through your body and very little is absorbed. If you touch it, a small amount may pass through your skin, but not usually enough to harm you.
