As industries expand globally, tungsten carbide has become a must-have for sectors that rely on high-durability and high-precision tools. But there’s a catch. Tungsten is a rare, finite resource. As costs rise and environmental concerns increase, industries must find sustainable ways to keep the tungsten flowing. The good news is that recycling tungsten carbide is not only possible, but it’s also profitable and good for the environment.
In this guide, we’ll talk about how to recycle tungsten carbide, its value, how it’s done, and where businesses can go to recycle their carbide waste efficiently.
So, Can Tungsten Carbide Be Recycled?
Yes, tungsten carbide can be recycled through processes like zinc melting, acid leaching, and direct collection of carbide scrap, transforming it into usable powder for new products. Recycling maximizes the valuable components of tungsten and cobalt, making the process sustainable and profitable.
Why Is Tungsten Carbide Recycling Worth It?
Recycling tungsten carbide is more than just environmentally responsible, it’s economically beneficial. Tungsten carbide is made up of tungsten, a rare and valuable metal, and cobalt, which adds significant market value. With cobalt prices fluctuating and the demand for tungsten carbide high in various industries, recycled tungsten can be a stable resource for production.
For companies in industries like automotive, aerospace, and industrial manufacturing, recycling tungsten carbide offers the chance to lower material costs, manage waste more effectively, and secure a sustainable supply chain. Tungsten carbide scrap is often sold at competitive rates, and buyers get high-quality material without the high extraction costs.
What Is The Scrap Value Of Tungsten Carbide?
The value of tungsten carbide scrap goes up and down based on how pure the carbide is and how much the market wants it. Right now, the average price for scrap carbide is around $5.32 per pound, but it can be all over the place. Some of the things that affect the price of scrap include:
Material Quality: The purity and condition of the material affects the price of scrap.
Market Demand: When demand for industrial and manufacturing tools is high, the price of scrap goes up.
Metal Content: If there’s a lot of cobalt and tungsten in the scrap, it’s worth more.
To get the most money, companies should sort and clean their tungsten carbide waste and call certified recycling centers to get a quote. Most of the time, recycled carbide is still hard and good enough to use in industrial applications, so companies can put high-value materials back into their manufacturing process.
How Is Tungsten Carbide Recycled?
Tungsten carbide recycling is done three main ways: the zinc process, acid leaching, and direct recycling. Each method has its own advantages and is used depending on the condition and makeup of the scrap.
1. Zinc Process
The zinc process, also called the zinc melting method, is a popular way to recycle carbide. Here’s how it works:
The tungsten carbide scrap is melted in a bath of molten zinc.
When the zinc gets into the carbide structure, it breaks it down into a powder.
The powder can then be taken out, washed, and separated from the zinc, leaving behind pure tungsten carbide particles that can be used again.
The zinc process is good for hard scrap, like tool bits and cutting tools, because it separates the materials and keeps their properties intact.
2. Acid Leaching
Acid leaching is a chemical recycling process that dissolves tungsten carbide in an acid solution, allowing tungsten to be recovered selectively. Here’s how it works:
You put tungsten carbide in a solution, usually made of nitric acid and hydrofluoric acid.
The acid reacts with the tungsten and cobalt in the carbide, breaking it down into a solution you can use.
You separate the tungsten and cobalt and refine them into a pure form that you can use in industry.
Acid leaching is good for stuff that’s got oil or other stuff on it because it makes a clean, high-quality product that you can use in sensitive applications.
3. Direct Recycling
Direct recycling is a simple and energy-efficient way to recycle tungsten carbide waste, like grinding sludge. Here’s how it works:
You sort carbide scrap from cutting and grinding.
You crush and grind the carbide into a fine powder.
You use heat treatments to get rid of the bad stuff, so you can use the powder to make new stuff.
Direct recycling is really green and lets manufacturers save money by getting carbide back from their own waste.
Is Tungsten Carbide Recycling Sustainable?
Tungsten carbide recycling is a way to be more sustainable in industry. Tungsten and cobalt are not unlimited, and recycling them means we don’t have to mine and refine as much. Here’s why tungsten carbide recycling is good for the environment:
Less Mining: By getting tungsten and cobalt back from waste, we don’t have to mine as much, which is hard on the earth and takes a lot of resources.
Less Energy: Recycling uses way less energy than getting stuff out of the ground and refining it.
Less Waste: Recycling centers can get tungsten out of industrial waste, so it doesn’t go in the landfill or mess up the environment.
For companies that want to be more sustainable, tungsten carbide recycling is a clear win because it saves resources, reduces waste, and helps make a circular economy.
Where Can You Recycle Tungsten Carbide?
To support industries all over the world, there are tungsten carbide recycling centers all over North America, Europe, and Asia, especially in places where they make a lot of stuff. Here are a few places you can go if you want to recycle your tungsten carbide:
1. Recycling Centers and Dealers: There are special recycling centers, often working with big tungsten carbide makers, that will buy your carbide scrap.
Example: Big recycling centers in the United States and Europe will take tungsten carbide waste from companies and usually give them a good price for it.
2. Manufacturer Partnerships: Some companies that make blades, like PassionBlade, can work with recycling people or set up their own recycling programs to handle their waste.
This is good for companies that make a lot of waste because they can get it picked up and taken care of.
3. Local Scrap Yards and Collectors: There are also smaller places and local people who will take tungsten carbide, which is good if you don’t have a lot to recycle.
4. International Recycling Programs: For companies that are all over the world, there are programs that let you recycle tungsten carbide across borders. Lots of places in North America and Europe work with global companies to take their tungsten scrap and process it.
Recycling tungsten carbide is not only possible, it’s a great idea for companies that are serious about sustainable manufacturing. By recycling, you can manage your costs, make sure you have a reliable supply of high-quality material, and be part of the global effort to be more sustainable. We advocate recycling tungsten carbide as part of our overall strategy to be more eco-friendly in industrial manufacturing.
If you’re interested in recycling tungsten carbide, you can reach out to certified recycling facilities, partner with established centers, or develop your own recycling process. It can make sure tungsten carbide has a more sustainable and resource-efficient future in industrial applications.
