The London Metal Exchange (LME) has decided to postpone its ban on tainted metal until 2025 in order to give producers additional time to comply with new guidelines. Tainted metal is the term used by the LME to describe metal that has been extracted by child laborers or involves the violation of human rights. The initial ban was in response to an upset regarding cobalt that was mined by children in Africa, and it was intended to commence in 2022. However, the deadline had to be pushed back because some producers are not willing to go along with the original guidelines.
