Understanding Zinc’s Role in a Low-Carbon Economy

When asked to describe how the metal zinc is used, people often mention vitamins, sunscreen, or metal coating.

But few are aware of zinc’s applications in transportation, infrastructure, electronics, food security, and renewable energy.

This graphic by Teck shows how zinc is playing a key role in the low carbon economy.

Zinc, the Versatile Metal

Zinc is one of the most versatile and essential materials known to mankind. It is the fourth most used metal in the world behind iron, aluminum, and copper.

The primary use of zinc is in the galvanizing process, which protects iron and steel from rusting. Zinc coatings play a key role in public transportation and infrastructure by extending the life of steel used in bridge rails and support beams, railway tracks, and public transportation hubs and terminals.

Additionally, zinc can be alloyed with other metals and used for die-casting into shapes such as door handles, alloyed with copper to make brass, and alloyed with copper and sometimes other metals to make some types of bronze, like architectural bronze or commercial bronze.

Zinc in the Low Carbon Economy

Furthermore, zinc also has applications in energy storage. Zinc-carbon batteries were the first commercial dry batteries, providing a higher energy density at a lower cost than previously available cells.

Due to its growing role in energy storage and its superior ability to protect metals against corrosion, zinc remains an essential material for the future.

Understanding Global Demand for Steelmaking Coal

Global population growth, increased urbanization, and a growing middle class will continue to drive long-term demand for steel and the steelmaking coal required to produce it.

The above infographic from Teck outlines the mineral’s key role in the low-carbon future.

A Vital Ingredient

Steel is the most commonly used metal and fulfills a variety of structural and construction needs, along with being an essential material for the production of vehicles, mechanical equipment, and domestic appliances.

Clean and renewable technologies also require steel to build wind turbines, solar panels, tidal power systems and bioenergy infrastructure.

While some kinds of steel can be made using recycled metal, roughly 72% of global steel production relies on steelmaking coal and certain higher grades of steel can only be made using the ingredient.

How is Steel Made?

Also known as metallurgical coal or coking coal, steelmaking coal is mined to produce the carbon used in steelmaking. This is fundamentally different from thermal coal, which is used to make steam that generates electricity.

To make steel, the coal is first heated at around 1100°C to remove water and other chemicals, without the (Read more...)

Visualizing America’s Electric Vehicle Future

Visualizing America’s Electric Vehicle Future

The U.S. is accelerating its transition to electric vehicles (EV) to address climate change. However, obtaining the minerals and metals required for EV batteries remains a challenge.

In this infographic from Talon Metals and Li-Cycle, we explore the country’s strategy to have vehicles, batteries, and key parts be made in the United States.

Then, we look at how this strategy could be fueled by domestic mining and battery recycling.

The All-Electric America

Gasoline-powered cars are one of the biggest sources of carbon pollution driving the climate crisis. As a result, the Biden Administration has set a target for EVs to make up 50% of all new car sales in the U.S. by 2030. Today, fewer than 1% of the country’s 250 million vehicles are electric.

In November 2021, Congress passed the Bipartisan Infrastructure Deal, which includes:

  • Replacing the government’s 650,000 vehicle motor pool with EVs.
  • Electrifying 20% of the country’s 500,000 school buses.
  • Investing $7.5 billion to build out a network of 500,000 electric vehicle chargers across the country.

The idea also has popular support. According to a poll, 55% of voters in the U.S. support requiring all new cars sold in their state to be electric starting in 2030.

However, rising EV sales are already driving demand for battery metals such as nickel, lithium, and copper, threatening to trigger a shortage of these key raw materials. So, does the U.S. have the (Read more...)

Visualizing Copper’s Role in a Low-Carbon Economy

Visualizing Copper’s Role in a Low-Carbon Economy

Climate change is top of mind for much of the world’s population.

The transition to renewable energy and electrification will require tons of metals, and copper is considered the most essential.

The above infographic from Teck outlines copper’s role in low-carbon technologies, highlighting why the red metal is essential for a low-carbon future.

Why Copper? 

Copper has been an essential material to man since prehistoric times. In fact, it is the oldest metal known, dating back more than 10,000 years and one of the most used because of its versatility.

The metal has four key properties that make it ideal for energy storage, propulsion for electrical vehicles (EVs), and renewable energy:

  • Conductivity: Copper has the highest electrical conductivity rating of all non-precious metals.
  • Ductility: Copper can easily be shaped into pipes, wires or sheets.
  • Efficiency: Copper’s thermal efficiency is about 60% greater than aluminum, so it can remove heat far more rapidly.
  • Recyclability: Copper is 100% recyclable and can be used repeatedly without any loss of performance.

In addition to its unique properties, copper remains relatively affordable, making it a key part of the energy transition.

A Cornerstone of the EV Revolution

EVs can use up to four times as much copper when compared to an internal combustion engine (ICE) passenger car. The amount goes up as the size of the vehicle increases: a fully electric bus uses between 11 and 18 times more copper (Read more...)
