environmental impact tantalum production

Tantalum in the environment ScienceDirect

Oct 01, 2017· In our modern economy, tantalum has become a ‘technology-critical element’ which is increasingly used in new technologies. This has led to a need to evaluate potential environmental impacts, which, in turn, requires knowledge of its concentration in the environment along with better understanding of the chemical processes underlying its environmental behaviour.

What Are the Dangers of Tantalum? Our Everyday Life

Reports that tantalum does not cause cancer are perhaps the most reassuring. In a study published by the National Institute of Environmental Health Sciences, muscles of rats were embedded with tiny pellets of uranium, lead, nickel or tantalum. All rats developed tumors except the tantalum recipients.

On the trail of tantalum: tracking a conflict mineral

Apr 20, 2016· Loch believes that, regardless of its direct impact, the Dodd-Frank reform has increased global awareness of the issue of conflict metals such as tantalum. He says that, while the NGO community did a very good job of convincing the public that electronics were the cause, the Dodd-Frank Act showed that this wasn’t necessarily the full picture.

Coltan mining and ethics Wikipedia

Coltan is the colloquial name for the mineral columbite-tantalum ("col-tan"); it is sometimes incorrectly used as shorthand for tantalite, a metallic ore from which the very similar elements niobium, also known as columbium, and tantalum are extracted. In the early 21st century coltan mining was associated with human rights violations such as child labour, systematic exploitation of the
