Today, most comes from hard rock deposits where gold is disseminated or associated with other metals and mined either through open pit or underground mining. Deposits form when gold is dissolved in hot pressurized fluids deep in the crust, and then transported upwards on fissures and cracks where it is deposited closer to surface.
90% of gold produced today is recovered through the cyanide leaching process.
There are three distinct streams that make up supply: official sales, recycled gold, and mine production.There has been a 571% increase in gold purchases from central banks from 2011 to 2010. Since the 2008 financial crisis, more people have opted to recycle gold as well. Recycling has increased 93% from 2002 to 2011.
Discoveries are declining and it is becoming more expensive to find gold. Data also shows that the grade of underground and open pit gold mines are decreasing over time.
The 50 Minerals Critical to U.S. Security
This graphic lists all minerals that are deemed critical to both the economic and national security of the United States.
The 50 Minerals Critical to U.S. Security
The U.S. aims to cut its greenhouse gas emissions in half by 2030 as part of its commitment to tackling climate change, but might be lacking the critical minerals needed to achieve its goals.
The American green economy will rely on renewable sources of energy like wind and solar, along with the electrification of transportation. However, local production of the raw materials necessary to produce these technologies, including solar panels, wind turbines, and electric vehicles, is lacking. Understandably, this has raised concerns in Washington.
In this graphic, based on data from the U.S. Geological Survey, we list all of the minerals that the government has deemed critical to both the economic and national security of the United States.
What are Critical Minerals?
A critical mineral is defined as a non-fuel material considered vital for the economic well-being of the world’s major and emerging economies, whose supply may be at risk. This can be due to geological scarcity, geopolitical issues, trade policy, or other factors.
In 2018, the U.S. Department of the Interior released a list of 35 critical minerals. The new list, released in February 2022, contains 15 more commodities.
Much of the increase in the new list is the result of splitting the rare earth elements and platinum group elements into individual entries rather than including them as “mineral groups.” In addition, the 2022 list of critical minerals adds nickel and zinc to the list while removing helium, potash, rhenium, and strontium.

The challenge for the U.S. is that the local production of these raw materials is extremely limited.
For instance, in 2021 there was only one operating nickel mine in the country, the Eagle mine in Michigan. The facility ships its concentrates abroad for refining and is scheduled to close in 2025. Likewise, the country only hosted one lithium mine, the Silver Peak Mine in Nevada.
At the same time, most of the country’s supply of critical minerals depends on countries that have historically competed with America.
China’s Dominance in Minerals
Perhaps unsurprisingly, China is the single largest supply source of mineral commodities for the United States.
Cesium, a critical metal used in a wide range of manufacturing, is one example. There are only three pegmatite mines in the world that can produce cesium, and all were controlled by Chinese companies in 2021.
Furthermore, China refines nearly 90% of the world’s rare earths. Despite the name, these elements are abundant on the Earth’s crust and make up the majority of listed critical minerals. They are essential for a variety of products like EVs, advanced ceramics, computers, smartphones, wind turbines, monitors, and fiber optics.
After China, the next largest source of mineral commodities to the United States has been Canada, which provided the United States with 16 different elements in 2021.
The Rising Demand for Critical Minerals
As the world’s clean energy transitions gather pace, demand for critical minerals is expected to grow quickly.
According to the International Energy Association, the rise of low-carbon power generation is projected to triple mineral demand from this sector by 2040.
The shift to a sustainable economy is important, and consequently, securing the critical minerals necessary for it is just as vital.
Visualizing China’s Dominance in Clean Energy Metals
Despite being the world’s biggest carbon emitter, China is also a key producer of most of the critical minerals for the green revolution.

Renewable sources of energy are expected to replace fossil fuels over the coming decades, and this large-scale transition will have a downstream effect on the demand of raw materials. More green energy means more wind turbines, solar panels, and batteries needed, and more clean energy metals necessary to build these technologies.
This visualization, based on data from the International Energy Agency (IEA), illustrates where the extraction and processing of key metals for the green revolution take place.
It shows that despite being the world’s biggest carbon polluter, China is also the largest producer of most of the world’s critical minerals for the green revolution.
Where Clean Energy Metals are Produced
China produces 60% of all rare earth elements used as components in high technology devices, including smartphones and computers.
The country also has a 13% share of the lithium production market, which is still dominated by Australia (52%) and Chile (22%). The highly reactive element is key to producing rechargeable batteries for mobile phones, laptops, and electric vehicles.
But even more than extraction, China is the dominant economy when it comes to processing operations. The country’s share of refining is around 35% for nickel, 58% for lithium, 65% for cobalt, and 87% for rare earth elements.
Despite being the largest economy in the world, the U.S. does not appear among the largest producers of any of the metals listed. To shorten the gap, the Biden administration recently launched an executive order to review the American strategy for critical and strategic materials.
It’s also worth noting that Russia also does not appear among the top producers when it comes to clean energy metals, despite being one of the world’s leading producers of minerals like copper, iron, and palladium.
Low Regulation in the Clean Metal Supply Chain
While China leads all countries in terms of cobalt processing, the metal itself is primarily extracted in the Democratic Republic of Congo (DRC). Still, Chinese interests own 15 of the 17 industrial cobalt operations in the DRC, according to a data analysis by The New York Times and Benchmark Mineral Intelligence.
Unfortunately, the DRC’s cobalt production has been criticized due to reports of corruption and lack of regulation.
Part of the Congolese cobalt comes from artisanal mines with low regulation. Of the 255,000 Congolese artisanal miners, an estimated 40,000 are children, some as young as six years old.
The Rise of Clean Energy Metals
The necessary shift from fossil fuels to renewable energy opens up interesting questions about how geopolitics, and these supply chains, will be affected.
In the race to secure raw materials needed for the green revolution, new world powers could emerge as demand for clean energy metals grows.
For now, China has the lead.
