Metals:
Australia is rich in minerals and is the world's largest producer of iron ore (essential for steel production) and lithium (key component in batteries); Source: Visual Capitalist
Most Mined Metals: Source: Visual Capitalist
iron ore (93.3% of total)
industrial metals (6.6% of total):
aluminum, chromium, copper, manganese, etc.
technology and precious metals (0.05%):
tin, rare earth oxides, molybdenum, cobalt, etc.
Cobalt: used for batteries; Democratic Republic of Congo: 75% of world’s cobalt supply; Source: Bloomberg
Titanium: important for defense, aerospace, automotives, and medicine; Source: Visual Capitalist
10 largest metal markets: Source: Visual Capitalist
iron ore, gold, copper, aluminum, nickel, zinc, silver, molybdenum, palladium, and lead
metals are important in infrastructure and energy
Iron and Steel

iron: world’s most mined metal; iron ore is primarily used to make steel; Source: Visual Capitalist
Steel
primarily used in construction, manufacturing, transportation, and energy sectors: strength, durability, and versatility; 25% of U.S. steel is imported; Source: Al Jazeera
steel: made from iron; used in cars, buildings, refrigerators, washing machines, cargo ships, surgical scalpels; it can be recycled over and over again; Source: World Steel Association
China is the world’s largest producer; Source: Visual Capitalist
Nickel
Lithium
electric vehicle batteries; Australia and Chile: top producers; Source: Visual Capitalist and Economist
rechargeable batteries, EV batteries, energy-storage systems; Source: USGS
devices: cell phones, cameras, toys, toothbrushes, and pacemakers; Source: Visual Capitalist
Albemarle: world’s largest lithium producer; Source: Lithium
Aluminum
Alcoa: America's largest aluminum producer; Source: Bloomberg
world’s 2nd most used metal (after iron): electronic devices, aircraft parts; Source: Visual Capitalist
important for transportation, packaging, construction, consumer durables, electrical transmission lines, and machinery; Source: USGS
Elements
zinc: primarily used in galvanization process: acts as a protective layer for iron and steel against corrosion; zinc coatings play a crucial role in public transportation and infrastructure by extending the life of steel used in bridge rails, support structures, railway trucks; Source: Visual Capitalist
cobalt: essential different technologies: electric vehicle batteries, portable devices (smartphones, tablets, and laptops), and jet engines; Democratic Republic of Congo is world’s largest producer (73% of global output); Source: Visual Capitalist and WSJ
nickel: essential for electric vehicle batteries; Source: WSJ
important for stainless steel, superalloys, and rechargeable batteries; Source: USGS
Copper
Chile (27%) and Peru (10%): world’s largest copper producers; Source: Visual Capitalist
critical for global energy transition and digital transformation: electric vehicles, renewable energy systems, data centers, AI infrastructure and smart grids; Source: UNCTAD
China: 60% of global copper ore imports + 45% of world's refined copper production: Source: UNCTAD
copper: essential for clean energy technologies: high electrical conductivity and durability (ensures effective transmission of electricity and heat: enhances overall performance and sustainability of technologies), high ductility, malleability, corrosion resistance, versatility, superior heat dissipation capabilities, 100% recyclability rate (can be reused multiple times without any performance declines), antimicrobial properties; Source: Visual Capitalist and Visual Capitalist and Visual Capitalist and Visual Capitalist
wind turbines, solar panels, EV batteries, infrastructure, clean energy, transportation, defense, consumer electronics, healthcare, currency, data centers
relationship with copper and gold prices: when one rises, the other tends to fall; in an economic downturn, for instance, gold climbs as investors seek a haven; copper prices dip as manufacturing and construction slow; Source: Visual Capitalist
Gold
delivered 10.9% annual return (on average) over past 25 years - driven by global crises that generated strong returns: 2008 financial crisis, COVID-19 pandemic, high inflation; Source: Visual Capitalist
gold mining is more energy-intensive and produces more emissions than silver mining; Source: Visual Capitalist
gold discovery mainly from 3 countries: China, Australia, South Africa; fabricated gold is used toward jewelry, computers, communications equipment, spacecraft, jet aircraft engines; Source: USGS

24 carat: pure gold with no other metals; Source: World Gold Council
America has the world’s largest gold reserves: more than 50% are stored at Fort Knox in Kentucky; Source: Visual Capitalist
countries maintain gold reserves for 3 key reasons; Source: Visual Capitalist
(1) stable and dependable store of value,
(2) currency stability
(3) diversification
U.S. central bank reserves (8,000 tonnes), China central bank reserves (2,200 tonnes: steadily increasing its reserves to diversify foreign exchange reserves away from U.S. Treasury bonds); Source: Visual Capitalist
Nevada accounts for 72% of America’s production; Source: Visual Capitalist
lack of new gold discoveries + stagnating gold production: casts doubts on future of gold supply; Source: Visual Capitalist
Silver
4 countries producing the most silver: Mexico, China, Peru, and Russia; Source: U.S. Money Reserve
silver: found in almost every electronic device with a switch or button: metal with the highest electrical conductivity; reputation as “safe haven” investment during economic turmoil; Source: Investopedia and Visual Capitalist
buy silver in 2 basic ways: as physical bullion or silver-backed securities; silver often performs in an opposite way to traditional securities so can be an invaluable way to diversify a portfolio; physical commodity: it has an intrinsic value which means its immune to inflation; Source: Business Insider
Rare Earths (REEs)
MP Materials (American company): Western Hemisphere's largest source of rare-earth minerals; Mojave Desert (across California and Nevada): Western Hemisphere's largest source of rare-earth minerals; Source: WSJ
17 metallic elements in periodic table made of scandium, yttrium, lanthanides; difficult and expensive to extract; everyday technologies (smartphones, wind turbines, LED lights), EV batteries, cancer treatments, MRI scanners, military equipment; Source: CNN
China: world's largest rare earth reserves (such as lithium and zirconium); Source: Statista
40% of known global rare earth reserves
