MY WORLD WILL COME TRUE: URANINITE

Jun 07, 2009 · Uraninite is mined using hard rock, openpit mining, or placer mining. Radon gas is produced when uranium is mined. If it is underground mining, it can be very dangerous unless the mine is well ventilated. If you breathe in a lot of radon gas, you can get lung cancer.

China Wrestles with the Toxic Aftermath of Rare Earth Mining

Jul 02, 2019 · Beginning in the 1990s, rare earth mining took off in this region, loed in Southeast China about 300 miles north of Hong Kong. As China began to produce more smartphones, wind turbines, electric vehicles, and other hightech products requiring rare earth elements, the mining intensified. But the removal of these elements from the earth's ...

What Is the Element Uranium Used For?

Jul 03, 2019 · Nuclear fuels are used to generate electrical power, to make isotopes, and to make weapons. Much of the internal heat of the earth is thought to be due to the presence of uranium and thorium. Uranium238, with a halflife of x 10 9 years, is used to estimate the age of igneous rocks. Uranium may be used to harden and strengthen steel.

What Is Pitchblende? (Uraninite)

Feb 05, 2019 · Pitchblende, also known by the name uraninite, is a mineral comprised mainly of oxides of the element uranium, UO 2, and UO 3. It is the primary ore of uranium. The mineral is black in color, like 'pitch'. The term 'blende' came from the German miners who believed it contained many different metals all blended together.

Cyanide Use in Gold Mining

Cyanide's efficiency makes mining more wasteful. Because cyanide leaching is very efficient, it allows profitable mining of much lower ore grades. Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used;
