11 Things Every Metal Investor Needs to Know About Zinc
Certain commodities tend to fly under the radar for periods of time.
For example, it was only in the last couple of years that markets have been able to digest the potential impact of the electric vehicle boom, and what it may mean for raw materials. The lithium, graphite, and cobalt prices reacted accordingly, and suddenly these essential ingredients for lithium-ion batteries were hot commodities.
Another one of those metals that comes and goes is zinc – and after shooting up in price over 35% this year, it definitely has the attention of many investors and speculators again.
Re-Thinking Zinc
Today’s infographic comes to us from Pistol Bay Mining, a company that is too focusing on zinc, and it highlights 11 things that investors need to know about a metal that is gaining substantial momentum.
Here’s why the metal is back in fashion:
1. Zinc is a $34 billion per year market.
It’s bigger than the silver ($18 billion), platinum ($8 billion), and molybdenum ($5 billion) markets combined. In fact, it is the fourth-most used metal worldwide.
2. Zinc smelting and production technology came way later than it did for other metals.
The ancients were able to smelt copper, lead, and iron, but it wasn’t until much later that people were able to work with zinc in any isolated state.
3. Even despite this, it was a crucial metal for ancient peoples.
They would smelt zinc-rich copper ores to make brass, which was used for many different purposes including weaponry, ornaments, coins, and armor.
4. Zinc is also crucial to produce many alloys today.
For example, brass is used for musical instruments and hardware applications that must resist corrosion. Solder and nickel-silver are other important alloys.
5. The world’s first-ever battery used zinc as an anode.
The voltaic pile, made in 1799 by Alessandro Volta, used zinc and copper for electrodes with brine-soaked paper as an electrolyte.
6. The metal remains crucial for batteries today.
Zinc-air, silver-zinc, zinc-bromine, and alkaline batteries all use zinc, and they enable everything from hearing aids to military applications to be possible.
7. Galvanizing is still the most important use.
About 50% of the metal is used in galvanizing, which is essentially a way to coat steel or iron so that it doesn’t rust.
8. China is both a major producer and end-user.
China mined 37% of the world’s 13.4 million tonnes of zinc production in 2015. It consumed 47% of the world’s supply that same year.
9. Major mines have been shutting down.
In 2016, China ordered the shutdown of 26 lead and zinc mines in parts of the Hunan province for environmental reasons. Meanwhile, Ireland’s Lisheen Mine and Australia’s Century Mine both shut down last year after being depleted of resources. That takes 630,000 tonnes of annual production off the table.
10. Stockpiles are dwindling.
Warehouse levels are less than half of where they were in 2013.
11. Zinc has been one of the best performing metals in 2016 in terms of price.
It started the year around $0.70/lb, but now it trades for $1.04/lb.

Gold mining is a global business, with hundreds of mining companies digging for the precious metal in dozens of countries.
But where exactly are the largest gold mines in the world?
The above infographic uses data compiled from S&P Global Market Intelligence and company reports to map the top 10 gold-producing mines in 2021.
Editor’s Note: The article uses publicly available global production data from the World Gold Council to calculate the production share of each mine. The percentages slightly differ from those calculated by S&P.
The Top Gold Mines in 2021
The 10 largest gold mines are located across nine different countries in North America, Oceania, Africa, and Asia.
Together, they accounted for around 13 million ounces or 12% of global gold production in 2021.
Rank | Mine | Location | Production (ounces) | % of global production |
---|---|---|---|---|
#1 | Nevada Gold Mines | 🇺🇸 U.S. | 3,311,000 | 2.9% |
#2 | Muruntau | 🇺🇿 Uzbekistan | 2,990,020 | 2.6% |
#3 | Grasberg | 🇮🇩 Indonesia | 1,370,000 | 1.2% |
#4 | Olimpiada | 🇷🇺 Russia | 1,184,068 | 1.0% |
#5 | Pueblo Viejo | 🇩🇴 Dominican Republic | 814,000 | 0.7% |
#6 | Kibali | 🇨🇩 Democratic Republic of the Congo | 812,000 | 0.7% |
#7 | Cadia | 🇦🇺 Australia | 764,895 | 0.7% |
#8 | Lihir | 🇵🇬 Papua New Guinea | 737,082 | 0.6% |
#9 | Canadian Malartic | 🇨🇦 Canada | 714,784 | 0.6% |
#10 | Boddington | 🇦🇺 Australia | 696,000 | 0.6% |
N/A | Total | N/A | 13,393,849 | 11.7% |
Share of global gold production is based on 3,561 tonnes (114.5 million troy ounces) of 2021 production as per the World Gold Council.
In 2019, the world’s two largest gold miners—Barrick Gold and Newmont Corporation—announced a historic joint venture combining their operations in Nevada. The resulting joint corporation, Nevada Gold Mines, is now the world’s largest gold mining complex with six mines churning out over 3.3 million ounces annually.
Uzbekistan’s state-owned Muruntau mine, one of the world’s deepest open-pit operations, produced just under 3 million ounces, making it the second-largest gold mine. Muruntau represents over 80% of Uzbekistan’s overall gold production.
Only two other mines—Grasberg and Olimpiada—produced more than 1 million ounces of gold in 2021. Grasberg is not only the third-largest gold mine but also one of the largest copper mines in the world. Olimpiada, owned by Russian gold mining giant Polyus, holds around 26 million ounces of gold reserves.
Polyus was also recently crowned the biggest miner in terms of gold reserves globally, holding over 104 million ounces of proven and probable gold between all deposits.
How Profitable is Gold Mining?
The price of gold is up by around 50% since 2016, and it’s hovering near the all-time high of $2,000/oz.
That’s good news for gold miners, who achieved record-high profit margins in 2020. For every ounce of gold produced in 2020, gold miners pocketed $828 on average, significantly higher than the previous high of $666/oz set in 2011.
With inflation rates hitting decade-highs in several countries, gold mining could be a sector to watch, especially given gold’s status as a traditional inflation hedge.

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
This was originally posted on Elements. Sign up to the free mailing list to get beautiful visualizations on natural resource megatrends in your email every week.
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.
