1. Coltan is a derived substance: Coltan is a combination of two minerals- columbite and tantalite. Its name ‘coltan’ is derived from this combination. The ore yields tantalum, an element used in modern electronic devices.
2. Popular usage: The tantalum extracted from coltan is used in a variety of everyday devices. It’s found in almost all modern electronic devices including cell phones, DVD players, video game systems, and computers. Tantalum makes excellent capacitors and can hold high electrical charge in a small size, making it perfect for compact mobile devices.
3. Centre of conflict: This mineral is at the heart of a deadly conflict in the Democratic Republic of Congo (DRC). Coltan mining in the DRC has been associated with serious human rights violations, including child labor, and the financing of armed conflict. Profits from the trade of conflict minerals, like coltan, are used to fund armed groups in the region.
4. Environmental concerns: Coltan mining is also harmful to the environment. Mines are typically dug by hand, which is not only dangerous but also labor intensive. Furthermore, the process destroys landscapes, pollutes water, and kills wildlife.
5. Efforts towards ethical sourcing: In recent years, pressure has been put on electronic manufacturers to ensure ‘conflict-free’ sourcing of Coltan. Several initiatives and regulations, including the Dodd-Frank Act in the United States, seek to decrease trade in conflict minerals. However, traceability remains a massive challenge.
