All the Metals We Mined in One Visualization
Metals are all around us, from our phones and cars to our homes and office buildings.
While we often overlook the presence of these raw materials, they are an essential part of the modern economy. But obtaining these materials can be a complex process that involves mining, refining, and then converting them into usable forms.
So, how much metal gets mined in a year?
Metals vs Ores
Before digging into the numbers, it’s important that we distinguish between ores and metals.
Ores are naturally occurring rocks that contain metals and metal compounds. Metals are the valuable parts of ores that can be extracted by separating and removing the waste rock. As a result, ore production is typically much higher than the actual metal content of the ore. For example, miners produced 347 million tonnes of bauxite ore in 2019, but the actual aluminum metal content extracted from that was only 62.9 million tonnes.
Here are all the metals and metal ores mined in 2019, according to the British Geological Survey:
| Metal/Ore | Quantity Mined (tonnes) | % of Total |
|---|---|---|
| Iron Ore | 3,040,000,000 | 93.57% |
| Industrial Metals | 207,478,486 | 6.39% |
| Technology and Precious Metals | 1,335,848 | 0.04% |
| Total | 3,248,814,334 | 100% |
Miners produced roughly three billion tonnes of iron ore in 2019, representing close to 94% of all mined metals. The primary use of all this iron is to make steel. In fact, 98% of iron ore goes into steelmaking, with the rest fulfilling various other applications.
Industrial and technology metals made up the other 6% of all mined metals in 2019. How do they break down?
Industrial Metals
From construction and agriculture to manufacturing and transportation, virtually every industry harnesses the properties of metals in different ways.
Here are the industrial metals we mined in 2019.
| Metal | Quantity Mined (tonnes) | % of Total |
|---|---|---|
| Aluminum | 62,900,000 | 30% |
| Manganese Ore | 56,600,000 | 27% |
| Chromium Ores and Concentrates | 38,600,000 | 19% |
| Copper | 20,700,000 | 10% |
| Zinc | 12,300,000 | 6% |
| Titanium (Titanium Dioxide Content) | 6,300,000 | 3% |
| Lead | 4,700,000 | 2% |
| Nickel | 2,702,000 | 1% |
| Zirconium Minerals (Zircon) | 1,337,000 | 1% |
| Magnesium | 1,059,736 | 1% |
| Strontium | 220,000 | 0.11% |
| Uranium | 53,400 | 0.03% |
| Bismuth | 3,700 | 0.002% |
| Mercury | 2,400 | 0.001% |
| Beryllium | 250 | 0.0001% |
| Total | 207,478,486 | 100% |
Percentages may not add up to 100 due to rounding.
It’s no surprise that aluminum is the most-produced industrial metal. The lightweight metal is one of the most commonly used materials in the world, with uses ranging from making foils and beer kegs to buildings and aircraft parts.
Manganese and chromium rank second and third respectively in terms of metal mined, and are important ingredients in steelmaking. Manganese helps convert iron ore into steel, and chromium hardens and toughens steel. Furthermore, manganese is a critical ingredient of lithium-manganese-cobalt-oxide (NMC) batteries for electric vehicles.
Although copper production is around one-third that of aluminum, copper has a key role in making modern life possible. The red metal is found in virtually every wire, motor, and electrical appliance in our homes and offices. It’s also critical for various renewable energy technologies and electric vehicles.
Technology and Precious Metals
Technology is only as good as the materials that make it.
Technology metals can be classified as relatively rare metals commonly used in technology and devices. While miners produce some tech and precious metals in large quantities, others are relatively scarce.
| Metal | Quantity Mined in 2019 (tonnes) | % of Total |
|---|---|---|
| Tin | 305,000 | 23% |
| Molybdenum | 275,000 | 21% |
| Rare Earth Elements | 220,000 | 16% |
| Cobalt | 123,000 | 9% |
| Lithium | 97,500 | 7% |
| Tungsten | 91,500 | 7% |
| Vanadium | 81,000 | 6% |
| Niobium | 57,000 | 4% |
| Cadmium | 27,500 | 2% |
| Tantalum | 27,000 | 2% |
| Silver | 26,261 | 2% |
| Gold | 3,350 | 0.3% |
| Indium | 851 | 0.06% |
| Platinum Group Metals | 457 | 0.03% |
| Gallium | 380 | 0.03% |
| Rhenium | 49 | 0.004% |
| Total | 1,335,848 | 100.00% |
Percentages may not add up to 100 due to rounding.
Tin was the most-mined tech metal in 2019, and according to the International Tin Association, nearly half of it went into soldering.
It’s also interesting to see the prevalence of battery and energy metals. Lithium, cobalt, vanadium, and molybdenum are all critical for various energy technologies, including lithium-ion batteries, wind farms, and energy storage technologies. Additionally, miners also extracted 220,000 tonnes of rare earth elements, of which 60% came from China.
Given their rarity, it’s not surprising that gold, silver, and platinum group metals (PGMs) were the least-mined materials in this category. Collectively, these metals represent just 2.3% of the tech and precious metals mined in 2019.
A Material World
Although humans mine and use massive quantities of metals every year, it’s important to put these figures into perspective.
According to Circle Economy, the world consumes 100.6 billion tonnes of materials annually. Of this total, 3.2 billion tonnes of metals produced in 2019 would account for just 3% of our overall material consumption. In fact, the world’s annual production of cement alone is around 4.1 billion tonnes, dwarfing total metal production.
The world’s appetite for materials is growing with its population. As resource-intensive megatrends such as urbanization and electrification pick up the pace, our material pie will only get larger.

Brass Rods: The Safe Choice
From airbags to firefighting equipment, components made from brass rods play a vital role in creating a safer environment.
Brass Rods: The Safe Choice
From airbags to firefighting equipment, components made from brass rods play a vital role in creating a safer environment.
This infographic from the Copper Development Association illustrates three use cases for brass. This is the first of three infographics in our Choose Brass series.
Why Brass?
Brass is one of the most reliable metals for industrial and other applications. It contains little to no iron, protecting it from oxidation, which can cause other materials to fail over time.
Additionally, the malleability of brass ensures tight and leak-free metal-to-metal seals for threaded joints, minimizing the risk of costly and dangerous system failures. Brass’s durability ensures critical system components function properly for years.
Brass for Safe Water Systems
Exposure to lead in water can cause various health problems, including neurological damage, developmental delays, and cardiovascular diseases.
As a result, the U.S. sets minimum health-effect requirements for chemical contaminants and impurities indirectly transferred to drinking water from products, components, and materials used in water systems.
Currently, only brass rod alloys are designated as “acceptable materials” according to national standards.
Brass is also essential for ensuring workplace safety, particularly in high-risk manufacturing environments.
Using Brass for Safe Manufacturing and Industrial Environments
Brass is used extensively in industrial applications such as machinery components, valves, fittings, architectural elements, bearings, and gears.
The machinability of brass rods also means longer tool life and higher productivity for manufacturers of precision parts.
The microstructure of brass helps break up metal chips generated during machining operations, preventing long and stringy chips that can crash machines and seriously injure operators.
Additionally, brass’s non-sparking properties make it ideal for tooling, fittings, and components in high-risk industries such as oil & gas, chemicals, pharmaceuticals, paint manufacturing, power plants, and explosives.
Brass for Safer Communities
Many pieces of equipment in our daily lives also rely on brass rod parts to function. Control valves in gas stoves, BBQs, and home furnaces made from brass rods reduce the risk of deadly gas leaks and fires.
Moreover, brass is ideal for firefighting equipment due to its corrosion resistance, durability, heat resistance, and non-sparking properties.
Fittings made from brass rods ensure that the brakes and airbags in our vehicles work when needed.
Brass and other copper-based alloys are also naturally antimicrobial, helping prevent diseases when used in high-touch surfaces such as door handles.
These are only some of the ways that brass rods help build a safer world for everyone.

The State of Copper Recycling in the U.S.
This graphic explores how recycling copper can help address the demand for the metal in the U.S.
The State of Copper Recycling in the U.S.
Copper is essential for a low-carbon economy due to its crucial role in renewable energy technologies.
As a result, many worry that a lack of the metal used in wires and batteries can hurt a transition to a green economy.
In this graphic, our sponsor, the Copper Development Association, explores how recycling can address the demand for copper.
Copper Scrap Recycled in the U.S.
In 2022, the total copper scrap recycled in the U.S. was approximately 830,000 tonnes, equivalent to 32% of the total U.S. copper supply for the same period. Around 670,000 tonnes (81%) originated from pre-consumer sources generated during manufacturing operations, while 160,000 tonnes (19%) came from post-consumer sources, such as obsolete products.
Brass and wire-rod mills accounted for the majority of the copper recycled from scrap (85%). Additionally, smelters, refiners, and ingot makers make 10% and chemical plants, foundries, and other manufacturers around 5%.
| Copper from Scrap | 2022 Content (tonnes) |
|---|---|
| Brass and wire-rod mills | 650,000 t |
| Smelters and refiners | 40,000 t |
| Ingot makers | 39,500 t |
| Foundries, Other | 40,000 t |
Despite the rising demand for copper, the U.S. predominantly exports its copper scrap.
In 2022, the U.S. exported half of the 1,569,000 tonnes of the copper content generated from scrap. This export trend persisted because, until recent years, the country lacked operating secondary copper smelters capable of processing complex scrap grades into furnace-ready raw materials.
However, reshoring this metal presents an opportunity for the country.
Tapping into the Urban Mine
North America currently has about 86 million tonnes (Mt) of copper in use, known as the Urban Mine. This copper will become available for recycling as aging infrastructure and products reach the end of their service lives:
- Buildings: 45.4 Mt
- Infrastructure: 16.1 Mt
- Consumer Products: 11.2 Mt
- Transport: 8.5 Mt
- Industrial Uses: 4.8 Mt
Increased secondary smelting and refining capacity is a crucial building block for a more resilient and self-sufficient U.S. copper supply chain.
In response to the growing need for copper, the U.S. plans to add over 280,000 tonnes of secondary smelting and refining capacity in the next few years. This expansion will enable the country to process more complex scrap grades domestically.
Given that copper products can last for decades, creating a lag time before the material becomes available for recycling, primary production will continue to play an important role in meeting the increasing needs in the U.S.
The Copper Development Association (CDA) brings the value of copper and its alloys to society to address the challenges of today and tomorrow. Visit www.copper.org to learn more about why copper is a critical mineral.
