| Technology description including background system | The process chain for REO production includes mining followed by beneficiation, calcination, extraction, and roasting stages, see Figure 2. The first step in REO production is mining, wherein crude ore is blasted and transported for further refining. Crude ore abstracted from the Bayan Obo mine is composed of both monazite and bastnasite. |
