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: 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. 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. 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. on Did you know that nearly one-fifth of all the gold ever mined is held by central banks? Besides investors and jewelry consumers, central banks are a major source of gold demand. In fact, in 2022, central banks snapped up gold at the fastest pace since 1967. However, the record gold purchases of 2022 are in stark contrast to the 1990s and early 2000s, when central banks were net sellers of gold. The above infographic uses data from the World Gold Council to show 30 years of central bank gold demand, highlighting how official attitudes toward gold have changed in the last 30 years.
Why Do Central Banks Buy Gold?
Gold plays an important role in the financial reserves of numerous nations. Here are three of the reasons why central banks hold gold:
Balancing foreign exchange reserves Central banks have long held gold as part of their reserves to manage risk from currency holdings and to promote stability during economic turmoil. Hedging against fiat currencies Gold offers a hedge against the eroding purchasing power of currencies (mainly the U.S. dollar) due to inflation. Diversifying portfolios Gold has an inverse correlation with the U.S. dollar. When the dollar falls in value, gold prices tend to rise, protecting central banks from volatility. The Switch from Selling to Buying In the 1990s and early 2000s, central banks were net sellers of gold. There were several reasons behind the selling, including good macroeconomic conditions and a downward trend in gold prices. Due to strong economic growth, gold’s safe-haven properties were less valuable, and low returns made it unattractive as an investment. Central bank attitudes toward gold started changing following the 1997 Asian financial crisis and then later, the 2007–08 financial crisis. Since 2010, central banks have been net buyers of gold on an annual basis. Here’s a look at the 10 largest official buyers of gold from the end of 1999 to end of 2021: Rank CountryAmount of Gold Bought (tonnes)% of All Buying #1🇷🇺 Russia 1,88828% #2🇨🇳 China 1,55223% #3🇹🇷 Türkiye 5418% #4🇮🇳 India 3956% #5🇰🇿 Kazakhstan 3455% #6🇺🇿 Uzbekistan 3115% #7🇸🇦 Saudi Arabia 1803% #8🇹🇭 Thailand 1682% #9🇵🇱 Poland1282% #10🇲🇽 Mexico 1152% Total5,62384% Source: IMF The top 10 official buyers of gold between end-1999 and end-2021 represent 84% of all the gold bought by central banks during this period. Russia and China—arguably the United States’ top geopolitical rivals—have been the largest gold buyers over the last two decades. Russia, in particular, accelerated its gold purchases after being hit by Western sanctions following its annexation of Crimea in 2014. Interestingly, the majority of nations on the above list are emerging economies. These countries have likely been stockpiling gold to hedge against financial and geopolitical risks affecting currencies, primarily the U.S. dollar. Meanwhile, European nations including Switzerland, France, Netherlands, and the UK were the largest sellers of gold between 1999 and 2021, under the Central Bank Gold Agreement (CBGA) framework. Which Central Banks Bought Gold in 2022? In 2022, central banks bought a record 1,136 tonnes of gold, worth around $70 billion.

China continued its gold-buying spree with 62 tonnes added in the months of November and December, amid rising geopolitical tensions with the United States. Overall, emerging markets continued the trend that started in the 2000s, accounting for the bulk of gold purchases. Meanwhile, a significant two-thirds, or 741 tonnes of official gold purchases were unreported in 2022. According to analysts, unreported gold purchases are likely to have come from countries like China and Russia, who are looking to de-dollarize global trade to circumvent Western sanctions.
