While United States Hibernated, China Salivated

When China tightened restrictions on rare-earth exports in October 2025, stunning the United States, it was the latest reminder of Beijing’s control over an industry vital to the world economy. China’s dominance was decades in the making. Since the 1990s, China has used aggressive tactics to build up and maintain its lock over rare-earth minerals, which are essential to making magnets needed for cars, wind turbines, jet fighters and other products. Beijing provided financial support to the country’s leading companies, encouraged them to snap up rare-earth assets abroad, and passed laws preventing foreign companies from buying rare-earth mines in China. It eventually consolidated its domestic industry from hundreds of businesses into a few giant players, giving it further leverage over prices…

In 1995, Chinese state-linked companies received U.S. government approval to buy the rare-earth materials and magnet business started by General Motors, called Magnequench. In the following years, the Chinese ownership shut down all its rare-earth plants in the U.S. and shipped the equipment to China. Top American engineers were offered opportunities to go to China and set up new plants there.  “There were some colleagues that were dead set against it, saying they would never help China learn our technology,” said one magnet expert who ultimately agreed to go to China. “When I arrived, I could not believe what I was seeing. The number of new factories being built, and the rate at which they were being built, was mind-blowing,” he said….  By the mid-2000s, the U.S. rare-earth industry had been all but wiped out. Mountain Pass, America’s major rare-earth mine, had been shut down, as had virtually all American facilities that processed rare earths and turned them into magnets. China produced around 97% of the world’s rare earths, giving it what was effectively a global monopoly…

By 2021, the U.S. government was growing more worried about China’s ability to weaponize rare earths, causing prices to jump. Washington began offering large-scale funding for new rare-earth plants, including a refinery in Texas to be built by Lynas, an Australian rare-earth company. But in 2021, the Association of China Rare Earth Industry issued a warning: to China’s leadership If Beijing wanted to maintain “China’s absolute dominant position,” the country needed to relax state production quotas. Beijing responded in 2022 by pushing up output by 25%, the most in years, with another large increase the following year. Prices tanked, hitting the bottom lines of Western producers and leading some to unload assets…Beijing also introduced new measures preventing the transfer of its rare-earth processing technology abroad.

The Real Green Energy Transition: Mining Minerals from Plants

Worries about China’s domination of critical minerals are driving Western scientists and companies to embark on increasingly novel ways to develop alternative sources. One such effort seeks to exploit a quirk of nature: Certain plants, called hyperaccumulators, absorb large quantities of minerals, like nickel and zinc, from the soil. Cultivating these plants, and then incinerating them for their metal, could provide U.S. companies with a small stream of domestically sourced minerals—without the expense and environmental destructiveness of conventional mining….At a greenhouse in Amherst, MA, scientists undertake gene editing to build a new fast-growing, nickel-absorbing oilseed plant. If successful, the plant could be used to harvest the metal from mineral-rich soils in states such as Maryland and Oregon…

Some 10 million acres of barren, nickel-rich soil are scattered around the U.S. In such areas, concentrations of minerals are generally too low to justify large-scale mining, but could offer opportunity for inexpensive nickel farming. In the case of nickel phyto-mining, as such efforts are known, the plants are dried and incinerated, leaving an ashy nickel concentrate. This concentrate can then be further purified and turned into battery-grade material.

To be sure, phytomining is small in scale. Companies in the field are targeting harvests of around 300 pounds of nickel per acre per year, roughly enough for six EV batteries. But the funding for nickel-farming plants is one small piece of a broad effort by the U.S. government to develop secure supplies of the minerals that are needed for defense and cutting-edge industry, and are an area where China is dominant.

The Environmental Harm Caused by the Energy Transition

In the electric-vehicle business, the quandary is known as the nickel pickle. To make batteries for EVs, companies need to mine and refine large amounts of nickel. The process of getting the mineral out of the ground and turning it into battery-ready substances, though, is particularly environmentally unfriendly. Reaching the nickel means cutting down swaths of rainforest. Refining it is a carbon-intensive process that involves extreme heat and high pressure, producing waste slurry that’s hard to dispose of. The nickel issue reflects a larger contradiction within the EV industry: Though electric vehicles are designed to be less damaging to the environment in the long term than conventional cars, the process of building them carries substantial environmental harm.

The challenge is playing out across Indonesia’s mineral-rich islands, by far the world’s largest source of nickel. These deposits aren’t deep underground but lie close to the surface, under stretches of overlapping forests. Getting to the nickel is easy and inexpensive, but only after the forests are cleared.  One Indonesian mine, known as Hengjaya, obtained permits five years ago to expand its operations into a forested area nearly three times the size of New York City’s Central Park. The mine’s Australian owner, Nickel Industries, said that rainforest clearing in 2021 caused greenhouse gas emissions equivalent to 56,000 tons of carbon-dioxide. That’s roughly equal to driving 12,000 conventional cars for a year, according to calculations by The Wall Street Journal based on U.S. Environmental Protection Agency data. “Unfortunately, land clearing is required for all open-cast mining processes, including our operations,” said the firm’s sustainability manager…. The negative impact is offset, he said, by nickel’s use in environmentally friendly batteries…Auto executives worried about having enough nickel to meet rapidly growing demand for EVs. They had moved away from cobalt, another battery component, after human-rights groups and journalists reported on widespread child labor in cobalt operations and dangerous conditions faced by miners in the Democratic Republic of Congo. Automakers tweaked their batteries to reduce cobalt by adding more nickel…

The nickel rush has created pressing new environmental concerns. The HPAL process used to process nickel pioneered by Chinese companies involves dousing nickel ore in sulfuric acid and heating it to more than 400 degrees Fahrenheit at enormous pressures. Producing nickel this way is nearly twice as carbon-intensive as mining and processing sulfide nickel found in Canada and Russia. Another way of processing laterite ore that often uses coal-powered furnaces is six times as carbon-intensive, according to the International Energy Agency. Companies also face questions about how to get rid of the processing waste. It is difficult to safely sequester in tropical countries because frequent earthquakes and heavy rains destabilize soil, which can cause waste dams to collapse. A 2018 Indonesian law allowed companies to obtain permits to discard mineral processing waste into the ocean….

China’s domination of Indonesian nickel processing poses risks for Western electric-vehicle companies at a time of fraying relations between Washington and Beijing. Last year, the U.S. government declared nickel a critical mineral whose supply is vulnerable to disruption, with very limited nickel production operations in the U.S.

Saving the Climate by Fouling the Oceans

The Norwegian government in June 2023 opened the door for deep-sea mining in its waters, despite opposition from environmental groups and a growing list of nation states arguing to ban the practice.  The government said it was proposing parts of the Norwegian continental shelf be opened for deep sea mining and other commercial seabed mineral activities…Companies and countries are scouring the planet to find and secure additional sources of metals and minerals critical for the energy transition, including cobalt, manganese and nickel.  To date deep-sea mining has focused on the extraction of seabed nodules—tennis-ball sized pieces of rock which contain manganese, cobalt and nickel, all of which are used in electric-vehicle batteries

So far much of the attention has centered on the Clarion Clipperton Zone in the Pacific Ocean: An area of water between Mexico and Hawaii that contains millions of tons of nodules.  In Norway however, the focus will be on seabed crusts on the country’s continental shelf. The target crusts contain copper, zinc and cobalt, as well as some rare-earth elements, according to the Norwegian Petroleum Directorate…

Countries including France and Germany have called for moratoriums on deep-sea mining, while in May 2023 a report found that when researching the pacific seabed, 90% of the more than 5,000 marine creatures found living in the Clarion Clipperton Zone were new species. Companies including Maersk and Lockheed Martin have also been divesting their deep-sea mining investments.

After the Oil Shock, the Metals Shock: fueling the green economy

Indonesia banned exports of nickel ore in 2020 in a bid to capture more of the metal’s value. As a result, exports of Indonesian nickel products were worth $30bn in 2022, more than ten times what they were in 2013. Nickel smelters have sprouted around the country, and makers of batteries, in which the metal is a key component, are building factories. On January 17, 2023 a cabinet official said the government was close to sealing deals with the world’s two largest makers of electric vehicles (EVS), Tesla and BYD, to build cars in Indonesia. Flushed with progress, the government is now thinking beyond nickel.

“This success will be continued for other commodities,” said Joko Widodo, Indonesia’s president, in December 2022. He confirmed that an export ban on bauxite, the ore used to make aluminum, was coming in June 2023. The bauxite industry is scrambling to prepare itself for the shock….The government has suggested that a ban on copper exports could be implemented next, with bans on tin and gold exports to follow.

The country’s pulling power in the global nickel market will be hard to replicate, though. Indonesia produces 37% of the world’s nickel. But its bauxite, gold and copper production is less than 5% of the global total…Bauxite smelters are also expensive and harder to build than nickel smelters. Local firms are struggling to raise the capital needed for them, often around 18trn rupiah ($1.2bn)…All the eight bauxite smelters are under construction are Chinese investments. . 

Indonesia’s resource nationalism also risks falling foul of global trade rules but Jokowi, Indonesia’s president  remains  undeterred. “This is what we want to do: be independent, independent, independent,” he said.

Congo, China and Battery Minerals

The demand of cobalt is bound to increase because of the batteries needed to power  electric vehicles (EVs).  Each battery uses about 10kg of cobalt. It is widely known that more than half of the world’s cobalt reserves and production are in one dangerously unstable country, the Democratic Republic of Congo. What is less well known is that four-fifths of the cobalt sulphates and oxides used to make the all-important cathodes for lithium-ion batteries are refined in China. (Much of the other 20% is processed in Finland, but its raw material, too, comes from a mine in Congo, majority-owned by a Chinese firm, China Molybdenum.)

On March 14t, 2018 concerns about China’s grip on Congo’s cobalt production deepened when GEM, a Chinese battery maker, said it would acquire a third of the cobalt shipped by Glencore, the world’s biggest producer of the metal, between 2018 and 2020—equivalent to almost half of the world’s 110,000-tonne production in 2017. This is likely to add momentum to a rally that has pushed the price of cobalt up from an average of $26,500 a tonne in 2016 to above $90,000 a tonne

South Korean and Japanese tech firms and it’s a big concern of theirs that so much of the world’s cobalt sulphate comes from China. Memories are still fresh of a maritime squabble in 2010, during which China restricted exports of rare-earth metals vital to Japanese tech firms. China produces about 85% of the world’s rare earths.

Few analysts expect the cobalt market to soften soon. Production in Congo is likely to increase in the next few years, but some investment may be deterred by a recent five-fold leap in royalties on cobalt. Investment elsewhere is limited because cobalt is almost always mined alongside copper or nickel. Even at current prices, the quantities needed are not enough to justify production for cobalt alone.

But demand could explode if EVs surge in popularity… the use of cobalt for EVs could jump from 9,000 tonnes in 2017 to 107,000 tonnes in 2026.  The resulting higher prices would eventually unlock new sources of supply. But already non-Chinese battery manufacturers are looking for ways to protect themselves from potential shortages. Their best answer to date is nickel.

The materials most commonly used for cathodes in EV batteries are a combination of nickel, manganese and cobalt known as NMC, and one of nickel, cobalt and aluminium known as NCA. As cobalt has become pricier and scarcer, some battery makers have produced cobalt-lite cathodes by raising the nickel content—to as much as eight times the amount of cobalt. This allows the battery to run longer on a single charge, but makes it harder to manufacture and more prone to burst into flames. The trick is to get the balance right.

Strangely, nickel has not had anything like cobalt’s price rise. Nor do the Chinese appear to covet it… Nickel prices plummeted from $29,000 a tonne in 2011 to below $10,000 a tonne 2017…. But by 2025 McKinsey expects EV-related nickel demand to rise 16-fold to 550,000 tonnes.

In theory, the best way to ensure sufficient supplies of both nickel and cobalt would be for prices to rise enough to make mining them together more profitable. But that would mean more expensive batteries, and thus electric vehicles.
