Silver Series Part 3: The World’s Growing Demand For Silver

Silver is the most versatile metal in the world. Not only does it have the highest thermal and electrical conductivity of all metals, but it also has many other impressive properties: silver is antibacterial, durable, reflective, and malleable.

With such a multitude of significant material qualities, it is no surprise that now more than half of silver used today is in industrial processes. Last year, it is estimated that 53% of silver was used in industry – an increase from a total of 46% a decade ago.


Perhaps the most notable industrial sector for silver demand is photovoltaics, where 2.8 million oz of silver is used for every gigawatt of solar energy capacity. The total installed capacity of solar globally is at around 178 GW in 2014, and growth in global installs is also significant, gaining 14% between 2013 and 2014.

The metal’s other main industrial uses include brazing and soldering as well as fabrication. In the former category, using silver for brazing and soldering helps produce leak-tight and corrosion-resistant joints when combining metal parts.

In terms of fabrication, silver-containing vehicles, batteries, and chemical processes are the most important categories for future growth. For use in automotive manufacturing, which has the highest project growth (4.9% CAGR) of categories other than solar, silver is used to coat electrical contacts to ensure the most efficient energy flow. Silver batteries, which have similar energy densities to lithium-ion batteries, are used in military and aerospace applications because they are more reliable and safe. Lastly, silver catalysts are also used to help combine ethylene and oxygen together to create ethylene oxide, which is used in medicine, anti-freeze, and cosmetics.


While industrial uses are the most prominent for the metal, it is investment that has been the real growth engine for silver demand over the last decade.

In 2014, 20% of all silver is used for investment purposes, compared to only 7% a decade ago. The demand for silver coins and bars has more than quadrupled since the early 2000s, and the coin sales of Canadian Maple Leafs and American Eagles have been soaring for years.

It is also interesting to note, especially at a time of such market vulnerability, that the ratio of silver to gold ounces bought in the market increases. This ratio peaked recently during the Global Financial Crisis in 2008, and in the last 12 months it has jumped up to comparable levels.


Jewelry is also a crucial market for silver, and the category is considered by some to serve as an investment and store of wealth as well. Lower prices for silver in recent years have helped jewelry rebound in Asia and the United States in particular.

Globally, silver jewelry fabrication experienced its second year of consecutive growth, increasing 1.5% to achieve a new record high. This was a reflection chiefly of the strong performance of silver jewelry demand from India, which surged 47% from 2013 levels.

A record of 7,063 tonnes of silver were imported to India in 2014, up 15% from 2013. The country imported more silver in November 2014 than they did in all of 2009. This is partially due to India’s rising population and per capital income, and also due to import restrictions on gold in the world’s second most populous country.


Silver demand is multi-faceted, with just over half of demand coming from industry and the rest split between mainly investment and jewelry demand. We will cover the historical returns of investing in silver in-depth with our final part of the Silver Series in the coming weeks.

Elements in the Earth’s crust provide all the basic building blocks for mankind.

But even though the crust is the source of everything we find, mine, refine, and build, it really is just scratching the surface of our planet.

After all, the innermost layer of the Earth, the core, represents 15% of the planet’s volume, whereas the mantle occupies 84%. Representing the remaining 1% is the crust, a thin layer that ranges in depth from approximately 5-70 km (~3-44 miles).

This infographic takes a look at what elements make up this 1%, based on data from WorldAtlas.

Earth’s Crust Elements

The crust is a rigid surface containing both the oceans and landmasses. Most elements are found in only trace amounts within the Earth’s crust, but several are abundant.

The Earth’s crust comprises about 95% igneous and metamorphic rocks, 4% shale, 0.75% sandstone, and 0.25% limestone.

Oxygen, silicon, aluminum, and iron account for 88.1% of the mass of the Earth’s crust, while another 90 elements make up the remaining 11.9%.

RankElement% of Earth's Crust
1Oxygen (O)46.1%
2Silicon (Si)28.2%
3Aluminum (Al)8.2%
4Iron (Fe)5.6%
5Calcium (Ca)4.1%
6Sodium (Na)2.3%
7Magnesium (Mg)2.3%
8Potassium (K)2.0%
9Titanium (Ti)0.5%
10Hydrogen (H)0.1%
Other elements0.5%

While gold, silver, copper and other base and precious metals are among the most sought after elements, together they make up less than 0.03% of the Earth’s crust by mass.

#1: Oxygen

Oxygen is by far the most abundant element in the Earth’s crust, making up 46% of mass—coming up just short of half of the total.

Oxygen is a highly reactive element that combines with other elements, forming oxides. Some examples of common oxides are minerals such as granite and quartz (oxides of silicon), rust (oxides of iron), and limestone (oxide of calcium and carbon).

#2: Silicon

More than 90% of the Earth’s crust is composed of silicate minerals, making silicon the second most abundant element in the Earth’s crust.

Silicon links up with oxygen to form the most common minerals on Earth. For example, in most places, sand primarily consists of silica (silicon dioxide) usually in the form of quartz. Silicon is an essential semiconductor, used in manufacturing electronics and computer chips.

#3: Aluminum

Aluminum is the third most common element in the Earth’s crust.

Because of its strong affinity for oxygen, aluminum is rarely found in its elemental state. Aluminum oxide (Al2O3), aluminum hydroxide (Al(OH)3) and potassium aluminum sulphate (KAl(SO4)2) are common aluminum compounds.

Aluminum and aluminum alloys have a variety of uses, from kitchen foil to rocket manufacturing.

#4: Iron

The fourth most common element in the Earth’s crust is iron, accounting for over 5% of the mass of the Earth’s crust.

Iron is obtained chiefly from the minerals hematite and magnetite. Of all the metals we mine, over 90% is iron, mainly to make steel, an alloy of carbon and iron. Iron is also an essential nutrient in the human body.

#5: Calcium

Calcium makes up about 4.2% of the planet’s crust by weight.

In its pure elemental state, calcium is a soft, silvery-white alkaline earth metal. It is never found in its isolated state in nature but exists instead in compounds. Calcium compounds can be found in a variety of minerals, including limestone (calcium carbonate), gypsum (calcium sulphate) and fluorite (calcium fluoride).

Calcium compounds are widely used in the food and pharmaceutical industries for supplementation. They are also used as bleaches in the paper industry, as components in cement and electrical insulators, and in manufacturing soaps.

Digging the Earth’s Crust

Despite Jules Verne’s novel, no one has ever journeyed to the center of Earth.

In fact, the deepest hole ever dug by humanity reaches approximately 12 km (7.5 miles) below the Earth’s surface, about one-third of the way to the Earth’s mantle. This incredible depth took about 20 years to reach.

Although mankind is constantly making new discoveries and reaching for the stars, there is still a lot to explore about the Earth we stand on.

Rare Earth Elements: Where in the World Are They?

Rare earth elements are the critical ingredients for a greener economy, making their reserves increasingly valuable to global supply chains.



Rare Earths Elements: Where in the World Are They?

Rare earth elements are a group of metals that are critical ingredients for a greener economy, and the location of the reserves for mining are increasingly important and valuable.

This infographic features data from the United States Geological Society (USGS) which reveals the countries with the largest known reserves of rare earth elements (REEs).

What are Rare Earth Metals?

REEs, also called rare earth metals or rare earth oxides, or lanthanides, are a set of 17 silvery-white soft heavy metals.

The 17 rare earth elements are: lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), promethium (Pm), samarium (Sm), europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Yb), lutetium (Lu), scandium (Sc), and yttrium (Y).

Scandium and yttrium are not part of the lanthanide family, but end users include them because they occur in the same mineral deposits as the lanthanides and have similar chemical properties.

The term “rare earth” is a misnomer as rare earth metals are actually abundant in the Earth’s crust. However, they are rarely found in large, concentrated deposits on their own, but rather among other elements instead.

Rare Earth Elements, How Do They Work?

Most rare earth elements find their uses as catalysts and magnets in traditional and low-carbon technologies. Other important uses of rare earth elements are in the production of special metal alloys, glass, and high-performance electronics.

Alloys of neodymium (Nd) and samarium (Sm) can be used to create strong magnets that withstand high temperatures, making them ideal for a wide variety of mission critical electronics and defense applications.

End-use% of 2019 Rare Earth Demand
Permanent Magnets38%
Glass Polishing Powder and Additives13%
Metallurgy and Alloys8%
Battery Alloys9%
Ceramics, Pigments and Glazes5%

The strongest known magnet is an alloy of neodymium with iron and boron. Adding other REEs such as dysprosium and praseodymium can change the performance and properties of magnets.

Hybrid and electric vehicle engines, generators in wind turbines, hard disks, portable electronics and cell phones require these magnets and elements. This role in technology makes their mining and refinement a point of concern for many nations.

For example, one megawatt of wind energy capacity requires 171 kg of rare earths, a single U.S. F-35 fighter jet requires about 427 kg of rare earths, and a Virginia-class nuclear submarine uses nearly 4.2 tonnes.

Global Reserves of Rare Earth Minerals

China tops the list for mine production and reserves of rare earth elements, with 44 million tons in reserves and 140,000 tons of annual mine production.

While Vietnam and Brazil have the second and third most reserves of rare earth metals with 22 million tons in reserves and 21 million tons, respectively, their mine production is among the lowest of all the countries at only 1,000 tons per year each.

CountryMine Production 2020Reserves% of Total Reserves
United States38,0001,500,0001.3%
South Africa-790,0000.7%
Other Countries100310,0000.3%
World Total243,300115,820,000100%

While the United States has 1.5 million tons in reserves, it is largely dependent on imports from China for refined rare earths.

Ensuring a Global Supply

In the rare earth industry, China’s dominance has been no accident. Years of research and industrial policy helped the nation develop a superior position in the market, and now the country has the ability to control production and the global availability of these valuable metals.

This tight control of the supply of these important metals has the world searching for their own supplies. With the start of mining operations in other countries, China’s share of global production has fallen from 92% in 2010 to 58%< in 2020. However, China has a strong foothold in the supply chain and produced 85% of the world’s refined rare earths in 2020.

China awards production quotas to only six state-run companies:

  • China Minmetals Rare Earth Co
  • Chinalco Rare Earth & Metals Co
  • Guangdong Rising Nonferrous
  • China Northern Rare Earth Group
  • China Southern Rare Earth Group
  • Xiamen Tungsten

As the demand for REEs increases, the world will need tap these reserves. This graphic could provide clues as to the next source of rare earth elements.
