Environmental Cost of Refineries
Some of the smaller rare earth smelting separation facilities do not have any kind of environmental protection at all. These are generally the small, illegal refineries and mines. 6 In China, saponification with ammonia is still used in rare earth refining, so a large amount of waste water is still produced.
