China's largest rare earth company by production volume; controls the Bayan Obo mining complex in Inner Mongolia — the world's largest rare earth deposit (light rare earths, primarily bastnäsite/monazite). Listed on Shanghai Stock Exchange. Subsidiary of Baotou Steel Group (itself a subsidiary of China Baowu, the world's largest steel company). Bayan Obo was initially developed as an iron ore deposit; rare earths were a 'byproduct' discovery that became the dominant geopolitical asset. China Northern's production plus other Chinese producers gives China ~60% of global ore production and ~85% of separated NdPr oxide.

Air Products and Chemicals (NYSE: APD; Allentown, PA; ~$12B revenue) licenses the APCI (Air Products and Chemicals, Inc.) natural gas liquefaction process technology used in many small- and mid-scale LNG liquefaction trains worldwide, including utility peak-shaving plants. The APCI propane pre-cooled mixed refrigerant (C3MR) process dominates large baseload LNG export trains globally (used in >90% of world's baseload LNG capacity), but Air Products also licenses adapted cycles for smaller peak-shaving applications. Air Products competes with Linde Engineering for small-scale liquefaction process technology licensing. Air Products is also the world's largest industrial gas producer, supplying nitrogen and other gases used in LNG facility construction and purging.
