Current mining and processing operations tend to have low recoveries, on the order of 50–80%, from ore to high-purity REE compounds. 5 Inefficient recovery is partly due to the low intrinsic value of the geologic resource compared with the processing costs. The processes for REE ores have been characterized by occasional major …
