RE's are cheap to dig, relatively speaking, and not rare at all. They're expensive because of the waste issues with Th, and the difficulty of getting them apart from one another - they tend to be all too chemically similar until you get to end use cases, like doping magnets, or making color phosphors for picture tubes (that demand is kinda gone now, and was for europium mostly). For those cases, small impurities of the other RE's mess up the end product.Neodymium is never found in nature as the free element, but rather it occurs in ores such as monazite and bastnäsite that contain small amounts of all the rare earth metals. The main mining areas are in China, the United States, Brazil, India, Sri Lanka, and Australia. The reserves of neodymium are estimated at about eight million tonnes. Although it belongs to the rare earth metals, neodymium is not rare at all. Its abundance in the Earth crust is about 38 mg/kg, which is the second highest among rare-earth elements, following cerium. The world's production of neodymium was about 7,000 tonnes in 2004.[7] The bulk of current production is from China, whose government has recently imposed strategic materials controls on the element, raising some concerns in consuming countries.[8]
Vast deposits of rare earth minerals, crucial in making high-tech electronics products, have been found on the floor of the Pacific Ocean and can be readily extracted, Japanese scientists said on Monday.
"The deposits have a heavy concentration of rare earths. Just one square kilometer (0.4 square mile) of deposits will be able to provide one-fifth of the current global annual consumption," said Yasuhiro Kato, an associate professor of earth science at the University of Tokyo.

According to the US Congressional Research service, world demand for rare earth elements is estimated at 136,000 tons per year, with production around 133,600 tons in 2010. The difference was covered by depleting stockpiles of previously mined material. World demand is projected to rise to at least 185,000 tons annually by 2015, and to top 200,000 well before the end of the decade.
The result has been soaring world prices. Some of the more prized rare earths trade at more than six times their 2009 prices on the global markets, and more than double domestic Chinese prices, according to data published by an Australian miner, Lynas Corp.

According to Technology Metals Research, an Illinois-based consultancy, there are at least 426 rare-earth projects under development by some 259 different companies in 36 different countries. Likely sources of new production can be found in Malaysia, Russia, Brazil and India - and at that old Mountain Pass mine in California.
Molycorp, which bought Mountain Pass from Chevron in 2008, went from a standing start to bringing in revenues of $US397m last year, mainly from processing existing stockpiles. The company is restarting mining activity and says it will be producing at an annual rate of 19,050 metric tons of rare earth oxide by the end of September.
David Abraham, a Jakarta-based resource analyst speaking to Reuters yesterday, said adding new global capacity was the only real way out of the impasse, WTO or no WTO.
"The world still faces a critical shortfall of certain rare earth elements," he said. "That's not a China problem, that's a global one."

A Congressional Research Service report on rare earth elements suggests the U.S. Defense Department has yet to fully appreciate the severity of the potential impacts a lack of domestic rare earths may have on U.S. weapon systems.
...
... The CSR asserts "the United States almost entirely lacks the refining, fabricating, metal-making, alloying, and magnet manufacturing capacity to process rare earths." The report highlights one U.S. company, Electron Energy Corporation, which manufactures SmCo permanent magnets, now using rare earths for which there is no U.S. production.
Among the elements needed to produce NeFeB rare earth magnets are small amounts of dysprosium and possibly terbium, the CSR observes. "Currently, dysprosium and terbium are only available from China."
"Clearly, rare earth supply limitations present a serious vulnerability to our national security," the Congressional Research Service noted. "Yet early indications are that the DOD has dismissed the severity of the situation to date."
The CRS report suggests Congress consider both short-range and long-range options for securing a source for rare earth elements as part of its oversight role in addressing U.S. national security interests.
Among the actions Congress could take are meeting with defense suppliers at all tiers of the supply chain "to ascertain their knowledge of material shortages and bottlenecks."
Congress could also require the DOD to convene the Strategic Materials Protection Board to define more rare earth elements as strategic to national security, the report advises. So far, the SMPB has only defined one rare earth element, beryllium as strategic to national security.
The report also suggests that Congress consider requiring a strategic rare earth element stockpile to increase the security of the U.S. domestic rare earths supply. "Congress may consider compiling a ‘virtual' stockpile database, with commitments and contracts with suppliers to buy the items when needed."
Other recommendations for congressional action contained in the report include: federal funding of downstream supply capacity where material shortfalls exist; and federal funding of rare earth application sciences in curriculums for military and other government institutes or in national research and development centers.
Should the DOD determine that rare earths fall into the classification of critical materials, CSR advises Congress could institute a new Critical Materials Program.
Finally, the report suggests, "Congress may encourage DOD to pursue joint ventures with other nations, as many other nations are seeking alternatives to a near total dependence on rare earths from China. However, the CRS advises, "It is critical for DOD to consider the implications of sourcing utilized by these partner nations. For example, if DOD relies on a partner nation for its rare earth metals, and that nation procures their oxides from China, this partnership may not provide the requisite security of supply."
Provincial and local officials in China's Guangdong Province have busted illegal rare earth mining operations, recovering 1,000 tonnes of illegally mined rare earths, as well as arresting 50 suspects.
...
The mines are spread across a large area in Guangdong, which makes them difficult to monitor for illegal activities, especially since illegal mining and smuggling of rare earths generate high profits, said Xiao Fangming, director of the Guangzhou Research Institute of Non-Ferrous Minerals.
Xiao has suggested strengthening the monitor of the rare earth separating plants in the province, which have a total combined capacity of 15,000 metric tons annually.
The government has approved the mining of 2,000 metric tons of rare earth oxides a year in Guangdong, but actual production surpassed 40,000 metric tons because of illegal mining.
... according to Renewables Consulting Group (RCG), “the use of REEs has faced criticism due to price volatility and political issues surrounding the supply chain.” Not to mention the millions of tons of acidic pollution generated by conventional extraction methods, and the renewable energy industry doesn’t look so green anymore. That is why Paul J. Antonick and Zhichao Hu, members of the thermodynamics team at the Rutgers University School of Engineering, came up with a natural solution.
They discovered a new way to get these elements out of phosphate rock waste – also known as phosphogypsum. They found out that mineral and organic acids – made by naturally occurring bacteria called Gluconobacter oxydanscould – can do the job instead of using harsh chemicals. If they can figure out a way to scale this new method up, it would mean less of a reliance on REE mining, as well as less, toxic chemicals usually deployed to extract the elements from metal ores. It would be a huge boost for clean energy development.
...
This study only looked at synthetic phosphogypsum produced in the lab. Next, they will test if this method also works on waste actually produced by the industry. Phosphogypsum is actually a waste by-product of phosphoric acid production for fertilizers. According to Futurity, “each year, the U.S. mines an estimated 250 million tons of phosphate rock to produce phosphoric acid for fertilizers.”
In other words, there’s a lot of it – about 100,000 tons of these REEs end up in phosphate rock waste every year. Theoretically speaking, the amount of waste produced means the annual production of rare earth oxides could be almost doubled if they can get this to work, even though the elements only make up about 0.1 percent of phosphate rock.

Global Times editor Hu Xijin, who has emerged as one of the most influential Communist Party mouthpieces since President Trump increased tariffs on $200 billion in Chinese goods, tweeted that China is "seriously considering restricting rare earths exports to the US."
...
Beijing has readied a plan to restrict exports of rare earths to the U.S. if needed, as both sides in the trade war dig in for a protracted dispute, according to people familiar with the matter.
The government has prepared the steps it will take to use its stranglehold on the critical minerals in a targeted way to hurt the U.S. economy, the people said. The measures would likely focus on heavy rare earths, a sub-group of the materials where the U.S. is particularly reliant on China. The plan can be implemented as soon as the government decides to go ahead, they said, without giving further details.

Canada’s Medallion Resources Ltd (MDL.V) ... said it is seeking proposals from contractors to help build a plant to process the metals from the reddish-brown phosphate mineral monazite, a sand containing high concentrations of rare earths.
The company has relationships with monazite suppliers in the U.S. Southeast, but likely would build its plant in the center of North America, eyeing the region between Texas and Saskatchewan, Chief Executive Officer Don Lay said in a an interview.

The company declined to provide financial figures for the project or lay out a timeline.

Since 2011, when Scott became the president and CEO of Littleton, Colorado-based Rare Earth Resources, the veteran mining executive and metallurgical engineer has been trying to get a massive stash of rare earth — a metallic element that's used in cellphones, electric vehicle batteries, fluorescent lights, defense, clean energy and much more — out of Bear Lodge, a small mountain range tucked away in the northeast corner of the state, about 40 miles from South Dakota's border.
According to mining experts, Bear Lodge is home to one of the richest and highest-grade rare earth deposits in the U.S., with an estimated 18 million tons of rare earth inside. Scott thinks there could be more than that. "It's an enormous, and enormously important, deposit," he says.
But despite efforts to get the metal out of the ground — Rare Earth Resources has been exploring the area since 2004, while others have tried here and there to mine it since the metal was first discovered in the area in 1949 — it remains stuck in the mountain. "It's a great resource," says Scott. "But we keep hitting a brick wall."
...
One issue is regulation — it takes a while to get the proper permits, says Scott. From 2010 to 2014, the company collected all sorts of environmental data, which it then showed to the U.S. Forest Service. In January 2016 it received a draft environmental impact statement from the government agency, which recommended that the project go ahead. Before it could receive the final impact statement, though, rare earth prices cratered — neodymium fell from about $85/kg to about $46 in 2016 (it's now at $75/kg) — and the project had to be put on hold.
...
In April, U.S. Senators Joe Manchin, Shelley Moore Capito and Lisa Murkowski introduced the Rare Earth Element Advanced Coal Technologies Act, which would allocate $23 million a year to the Department of Energy and its National Energy Technology Laboratory (NETL) through 2027 to help develop technologies that could extract rare earth elements from coal and coal by-products in U.S. mines.

Canada will have rare earth processing plant in operation by the end of 2022 as the province of Saskatchewan has committed C$31 million (about $24m) to build the facility, which aims at boosting domestic supply of the key ingredients for military weapons, electric vehicles and smartphones.
The process of turning rare earth elements (REE) ore into individual products is done in two main stages. The first is the concentration of ore to mixed REE Carbonate. The second is the more complex separation stage that converts the mixed REE Carbonate to commercial pure-grade REEs. The facility, owned and operated by the Saskatchewan Research Council (SRC), will address both stages of REE processing.
The province said it would be the first of its kind in Canada, adding that it is expected to be an industry model for future commercial rare earth expansion.
...
Setting an independent domestic rare earth and critical minerals supply chain has become a priority for Canada and, particularly, the United States. Both currently rely on China, which accounts for 70% of global production.
...
The 69,000 square foot plant will be located in north Saskatoon and will employ about two-dozen people. The facility is expected to be fully operational in late 2022 with construction beginning this fall.
