The Hidden Value of Recycling Exotic Metals: What You Need to Know

Did you know your old electronics, used batteries, and industrial scrap may contain a hidden gem? This hidden gem we speak of is recycling exotic metals. It’s true—there could be gold in your garbage and we want to help you strike it!

Intrigued? Then you don’t want to miss what we have to share today. In this article, we will explore the fascinating world of exotic metal recycling and the untapped value of it that most people do not know about.

What Are Exotic Metals?

These so-called rare metals are elements that are typically found only in trace quantities in the Earth’s crust. These are metals, such as tungsten, cobalt, lithium, tantalum, and rare earth elements like neodymium and europium.

However, more well-known materials, including some grades of stainless steel and titanium, are also exotic metals.

They often serve as fundamental building blocks for much of the technology we rely on each day, including smartphones to electric vehicles. They are also used for aerospace and defense purposes, too.

Because they are so scarce and increasingly in demand for electronics, some rare metals can fetch a small fortune. Nevertheless, the most common methods to extract, process, and purify these metals are potentially environmentally harmful and are constituted by some of the most energy-intense activities. Thus, recycling is a necessary practice.

How: Recycling Exotic Metals

Does rarity spoil the ease of recycling? Although it’s not necessarily as simple as recycling standard materials, it’s still possible, and it can be a lucrative venture.

Here is a basic outline of how the process works:

Step 1: Collection and Sorting

The first step is to collect and sort materials that contain exotic metals. We’ll tell you more about the best sources for exotic metals in a moment, but they include electronic waste, industrial scraps, and used batteries.

Step 2: Processing the Materials

There are a few different processing methods depending on the specific metal you’re recycling, but they often include:

  • Mechanical Processing: Shredding and grinding the materials to break them into a manageable size.
  • Chemical Processing: Chemicals are applied to dissolve and separate required metals apart from other materials.
  • Pyrometallurgical Processing: This is a method of high-temperature processing that can melt and separate metals.
  • Hydrometallurgical Processing: Aqueous solutions help extract metals from ores or recycled materials.

Step 3: Purification and Refining

After the finished metals have been extracted, these need to be purified and refined to make sure the new material meets the standards for re-use.

Step 4: Re-Entry into the Supply Chain

A final step sends purified metals back into the supply chain to be put to use making new high-tech products, including EV batteries.

The Why: Perks of Exotic Metal Recycling

There are many advantages to recycling rare metals, both environmental and economic.

Environmental Benefits

  • Less mining and extraction: Recycling lessens the need for new mining and extraction processes that can be detrimental to the environment.
  • Lighter carbon footprint: Recycling metals uses far less energy than metal production from virgin ore, and the result is a lighter carbon footprint.
  • Preservation of natural resources: Recycling is necessary to ensure there are resources left for future generations to use.

Economic Benefits

  • Save money: Exotic metal recycling can be more affordable than mining and processing new materials, translating into huge cost savings for companies.
  • Make money: Departments within your organization can actually create a new revenue stream through the sales made to metal recycling companies. Because recycling is a source of critical materials, there are supply chain security implications that are perhaps more appealing than the environmental incentives for recycling.

How to Recycle Exotic Metals

It can be difficult to find out where to recycle rare metals, but before you start, there are several programs you can consider:

  • Partner with e-waste recycling programs: E-waste recycling programs specialize in extracting and recycling metal from electronics. Often, these electronics contain the exotic metals you’re eager to recycle.
  • Industrial recycling services: Turn to industrial recycling services that are equipped to recycle large amounts of scrap metal and are capable of processing exotic metals. Enlisting the help of experts can take a lot of the work out of the process for you, ensure the exotic metals are properly handled and extracted, and even help you maximize your earnings.
  • Recycle batteries: Look for nearby battery recycling efforts. Some batteries, like lithium and cobalt, are often laced with high-grade exotic metals.

Common Sources of Exotic Metals for Recycling

If you’re interested in either learning more about exotic metal recycling or starting your own program, it’s helpful to first understand some of the best sources of exotic metals and other precious resources.

Smartphones and Tablets

Smartphones and tablets are one of the richest sources of exotic metals, but they’re also one of the most under-utilized. In fact, of the estimated 150 million phones Americans throw out each year, less than 5% of those with lithium-ion are recycled!

Electric Vehicle Batteries

Electric vehicle batteries are a rich source of lithium, nickle, and cobalt. Fortunately, recylcing technology can now recover an average of more than 95% of materials in these lithium-ion batteries. Upon recycling, they can go back into the supply chain. Then, they can help create new EV batteries or other energy storage products.  

Aerospace Components

Many aerospace components contain exotic metals like titanium and tungsten.

For its part, tungsten boasts impressive mechanical and physical properties. With that in mind, it is often used to make alloy counterweights. These counterweights necessitate precise weight distribution, and tungsten gets the job done. It helps reduce vibration from mass imbalances that aircraft engines or propeller systems might experience.

Tungsten alloy rotor blades are also commonly used in aerospace, particularly for satellite and helicopter rotor blades, missiles, and aerospace gyro control. Interesting, these alloy rotor blades can also help reduce vibration from riveting guns which can help aerospace workers prevent carpal tunnel syndrome.

Medical Devices

Some medical equipment contains exotic metals.

For example, lab crucibles and tongs are often made with platinum. Electrophysiology catheters are also tipped in platinum. Medical imaging, including X-rays, CT scans, and MRI films, also have silver in them, and there are even businesses that specialize in silver recovery from X-rays.

Industrial Machinery: This may contain a variety of exotic metals used in specialized components.
