The Responsible Mica Initiative (RMI) is a global coalition for action – putting policy into practice – comprised of multiple organizations committed to establishing a fair, responsible and sustainable mica supply chain in the states of Jharkhand and Bihar in India that will eliminate unacceptable working conditions and eradicate child labor by 2030.
The term mica refers to the 37 phyllosilicate minerals that occur in a layered or plate-like structure. The most commercially important variants of mica are muscovite and phlogopite. Mica is mined in more than 35 countries. While there is competing and incomplete data on precise production volumes, due in part to the informal economy that is involved in mica mining in some countries, the consensus is that India and Madagascar are the two largest sources of mica followed by China and Brazil.
