- Based on local iron ore from Paiyun-opo and coal from Shih-kuai-kou, and again with ‘all-round Soviet assistance’, Pao-t’ou has been made the largest steel town on the Mongolian Plateau [26]. The role it was about to play became clear when the construction of the Pao-t’ou—Lan-chou Railway was begun in 1954 and, like that of several other vital lines, was completed well ahead of schedule [27].]

- 2022 March 18, Brugger, Joël; Barbara Etschmann; Marion Louvel, “Powerful X-rays reveal the birth of giant rare earth element deposits – and may give clues for sustainable mining”, in The Conversation, archived from the original on 18 March 2022:
- All rocks around us contain significant amounts of rare earth elements, but they become concentrated in these exotic magmas through slow crystallisation in Earth’s crust. This is usually not enough to make an ore deposit, which consists of millions of tonnes of rock made up of between 5 and 50% by weight of rare earth elements. A second step of concentration is required.
In giant deposits such as Bayan Obo in Inner Mongolia, hot fluids loaded with carbonate appear to have undergone this extra concentration step. But exactly how has been a mystery.
