Mining and processing of REY can create a number of environmental risks to both human health and environment. The problem with rare earth mining is that the REY ores contain different metals in their structure including aluminium, arsenic, barium, cadmium, radioactive materials, like uranium and thorium, etc. and thus, depending on the REY-bearing ore, there is variation in
