Cobalt poisoning is intoxication caused by excessive levels of cobalt in the body. Cobalt is an essential element for health in animals in minute amounts as a component of vitamin B 12 . A deficiency of cobalt, which is very rare, is also potentially lethal, leading to pernicious anemia .
These elements include vanadium, manganese, iron, cobalt, copper, zinc, selenium, strontium and molybdenum. [75] A deficiency of these essential metals may increase susceptibility to heavy metal poisoning. [76] Selenium is the most toxic of the heavy metals that are essential for mammals. [77]
An aspirational method of decontamination of heavy metals is phytoremediation or bioremediation, but these approaches have solved few real world problems. Toxic metals can bioaccumulate in the body and in the food chain. [5] Therefore, a common characteristic of toxic metals is the chronic nature of their toxicity.
Around 75 per cent of the world’s cobalt is mined in the DRC -- and the world cannot get enough of it. The rare, silvery metal is an essential component to every lithium-ion rechargeable battery ...
The Australian owner of a cobalt mine in Central Idaho plans more extensive study of cobalt at a remote site in the Salmon River Mountains, and the potential for a cobalt refinery, after securing ...
[73] [74] The impact on the world cobalt economy from this conflict was smaller than expected: cobalt is a rare metal, the pigment is highly toxic, and the industry had already established effective ways for recycling cobalt materials. In some cases, industry was able to change to cobalt-free alternatives.
The Mutanda Mine (French: Mine de Mutanda) is an open-pit copper and cobalt mine in the Lualaba Province of the Democratic Republic of the Congo (DRC). It is the largest cobalt mine in the world. Accidents and spills at the mine have killed workers and polluted nearby rivers and fields.
