Even in the legal markets, coltan mining is environmentally dangerous. Developing nations often go through with mining operations because they need the capital these operations bring without thinking of the environmental impacts.

Overview. Unregulated mining has the potential to release harmful substances into the soil, air, and water. Mission 2016 proposes that governments enforce regulations on companies and use cutting-edge technology to reduce the damage from mining-related sources.here is no ore dust or direct ore exposure to the environment and a lower consumption of water is needed in the mining process (International Atomic Energy Agency [IAEA], 2005). However, the strong acids used to dissolve the ore body commonly dissolve metals in the host rock as well.
