Radioactive cobalt-60 is used to treat cancer and, in some countries, to irradiate food to preserve it. Cobalt is an essential trace element, and forms part of the active site of vitamin B12.
Where is cobalt found?
Cobalt is not found as a free element, but is found in minerals in the Earth’s crust. Cobalt ores include erythrite, cobaltite, skutterudite, and glaucodot. The majority of cobalt is mined in Africa and is a byproduct of the mining of other metals including nickel, copper, silver, lead, and iron.
Why is cobalt bad?
As you decrease the amount of cobalt, you increase the amount of nickel. The cells can overheat and it can no longer effectively cool itself, which can lead to combustion. That’s a relatively low risk but it’s not a risk that can be taken and you need special technology to avoid that.
Who produces cobalt?
the Democratic Republic of Congo The mining industry in the Democratic Republic of Congo is the most lucrative and essential part of the DRC economy. It is their largest source of export income. The DRC accounted for nearly two thirds of global cobalt production in 2020, making them the world’s largest cobalt producer by a large margin.

A deficiency of cobalt, which is very rare, is also potentially lethal, leading to pernicious anemia. Exposure to cobalt metal dust is most common in the fabrication of tungsten carbide. Another source is from wear and tear of certain metal-on-metal hip prostheses. …
What products is cobalt found in?
Cobalt is an essential raw material for superalloy, cemented carbide, diamond tool, batteries, anticorrosive and magnetic materials. It is widely applied in fields including aerospace, electronic appliances, machinery manufacturing, automobiles, chemical industry, agriculture, ceramics, etc.
Is cobalt a precious metal?
Precious metals are very rare metals that also have desirable characteristics – like their ability to make beautiful jewelry. Eight metals are deemed precious: silver, gold, platinum, palladium, rhodium, ruthenium, iridium, and osmium. … Among these contemporary metals are titanium, tungsten, and cobalt.
Why is cobalt expensive?
Political instability has historically influenced the price of cobalt ore. … Current battery technologies require cobalt as part of the cathode. Given the growing popularity of electric vehicles, demand for cobalt continues to increase. Near-term trends suggest demand will outstrip supply, thus increased prices.
How is cobalt refined?
Production of Cobalt Cobalt naturally occurs in nickel-bearing laterites and nickel-copper sulfide deposits and, thus, is most often extracted as a by-product of nickel and copper. … Cobalt metal can then be refined from this using electrolysis, before being crushed and degassed to produce a pure, commercial-grade metal.
How much cobalt is in the world?
According to the US Geological Survey (USGS), total cobalt reserves worldwide stand at an estimated 7.1 million tonnes, with 140,000 tonnes produced globally in 2020.

Does Tesla use cobalt?
Their new range of 4680 batteries intended for the new generation of Tesla cars do not use nickel-manganese-cobalt cathode but a high-nickel cathode.
Is cobalt more expensive than gold?
Cobalt Affordability Cobalt is a relatively affordable metal and compared to the precious metals, it’s easy on your pocket. It is more expensive than metals such as titanium or tungsten, but is less expensive than gold or platinum.

What diseases can cobalt cause?
Cobalt is toxic to the heart muscle. It can cause heart muscle disease (toxic cardiomyopathy) after too much exposure. An increase in red blood cells (polycythemia) may be a symptom of too much cobalt. Not treating this issue can cause congestive heart failure.
What are the symptoms of too much cobalt?
Symptoms of High Cobalt Levels in Blood
- Cardiomyopathy (heart problems), including heart failure.
- Depression and other mental health conditions.
- Visual impairment that may lead to blindness.
- Cognitive impairment.
- Nerve problems, such as peripheral neuropathy.
- Thyroid problems.
- Auditory impairment, tinnitus, deafness.
What happens if you eat too much cobalt?
Other health effects associated with exposure to high levels of cobalt through ingestion may include: nausea and vomiting, vision problems, dermatitis, thyroid damage, severe damage to the heart, and even death.
Is milk high in cobalt?
Some of the dietary sources that are abundant in cobalt include red meat, milk, fish, cabbage, figs and turnips.

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
