"According to a joint Amnesty International and African Resources Watch report,
[5] Congo DongFang International Mining, a subsidiary of Huayou Cobalt, sources cobalt from primitive "artisanal" mines in the Democratic Republic of the Congo, where there are few worker protections and child labor has been employed.
[6][7]Apple Inc. said that approximately 20% of the lithium in Apple's batteries were sourced from Huayou Cobalt."
