Thorium can be strip mined and it could be deep mined. It is be produced as a byproduct of the production of rare earth elements, and since the current production as a byproduct far exceeds the demand, it is not usually mined.
Thorium was discovered in 1828 in Sweden by the well-known chemist Jöns Jakob Berzelius.
no
No it is not found . Monazite sand usually contains thorium.
Lignite used/mined in in 1850-1950 (estimated)
The "analyze and draw conclusions" step of the scientific method is based on gathered data.
United States has thorium reserves of approx. 160 000 t.
Thorium is extracted from minerals as monazite, thorianite, thorite, the mineral is grounded, dissolved in nitric acid, thorium is extracted with tributylphosphate. Also other methods exist.Pure thorium is obtained from ThO2 by a calciothermic process, from ThI2 by thermal decomposition or from ThF4 by electrolysis.
Thorium is typically mined as a byproduct of rare earth element mining, with the largest producers being China, Brazil, India, and the United States. These countries have significant reserves of thorium and extract it during the process of mining for other minerals.
Iron is gathered by making use of the magnet. Iron is usually mined as iron ore. Since it is magnetic, a magnet is used to separate it from the other foreign particles.
Common compounds of thorium: thorium dioxide, thorium trifluoride, thorium tetrafluoride, thorium tetrachloride, thorium triiodide, thorium diiodide, thorium tetraiodide, thorium nitrate, thorium oxalate, thorium carbide, thorium sulfides, thorium nitride, thorium oxinate, etc.
Thorium and fluorine Thorium trifluoride - ThF3 Thorium tetrafluoride - ThF4
Hazards and Health Considerations: Thorium presents both a toxic and radiological hazard. Toxicologically, it causes heavy metal poisoning similar to lead or the uranium isotopes. Biologically, thorium accumulates in the skeletal system where it has a biological half-life of 200 years, the same as plutonium. An M 17 protective mask and standard anti-contamination clothing will adequately protect against thorium.
Thorium is a natural, radioactive, chemical element; chemically, thorium is homogeneous.
Protactinium is not typically mined directly because it is a rare element found as a trace product of the decay of uranium and thorium. It is usually produced as a byproduct of nuclear reactions or through the decay of uranium ore.
Also thorium.
The chemical symbol of thorium is Th.
232Th has 142 neutrons and 90 protons and electrons.
