Dec 08, 2020 Coal-fired electricity generation is the process of making electric power from the energy carbon stored in coal. The process of converting coal into electricity has multiple steps 1. A machine called a pulverizer shown below grinds coal into a fine powder. 2. The coal powder mixes with hot air, which helps it burn more efficiently. read more

Compared to coal and other hardrock mining, the scope of REE mining has always been very small, both in the U.S. and globally. No major REE mining operations have been conducted in the U.S. since 1995. Mining and processing activities have the potential to create a number of environmental risks to human health and the environment.
