Rare earths

In the years before 2015 the US mined rare earths but this was shut down because of environmental concerns. The one US plant now mines the ore and ships it to China for processing. As the demand for these metals increased China gained a strangle hold on production and in the past couple of years the US has taken steps to get into the market. A company called Lynas had a mine in Australia and agreed to build a plant in Texas. They received money from the DOD to process 5,000 tons per year of rare earths. In December of 2019 the USA Rare Earth and Texas Mineral Resources Corp Announce Opening of First Heavy and Light Rare Earths Processing Facility Outside of China Will environmental concerns interfere with the building of this facility?
