F OREWORD. Mining and environment — the two do not seem to go together. Indeed, they seem almost antithetical. Whether one reads about small-scale gold mining in the Amazon or huge coal mines in North America, whether simple sand and gravel pits or complex metallurgical operations, the legacy of the mining industry appears to be destruction of land and pollution of air and water.

For every ton of rare earth produced, the mining process yields 13kg of dust, 9,600-12,000 cubic meters of waste gas, 75 cubic meters of wastewater, and one ton of radioactive residue. This stems from the fact that rare earth element ores have metals that, when mixed with leaching pond chemicals, contaminate air, water, and soil.
