How to Recycle Magnesium?

Magnesium is a versatile metal that has become increasingly popular due to its light weight, strength, and corrosion resistance. It is used in various products, including automobiles, aircraft, and electronic devices, to name a few. However, as with any metal, the extraction and refinement processes required to produce magnesium are energy-intensive and generate harmful waste. Recycling Magnesium is a great way to reduce this environmental impact, as it allows the reuse of existing resources while minimizing the need for additional extraction. In this blog, we will explore the benefits of recycling magnesium, how to do it, and best practices for ensuring the highest quality of recycled magnesium.

What is Magnesium?

Magnesium is an important mineral essential for the support of various bodily functions. It helps to maintain normal nerve and muscle function, supports a healthy immune system, keeps our bones strong, and is necessary for energy production. Magnesium also supports cardiovascular health and can help reduce stress levels due to its calming properties. Research has shown that magnesium may help protect against chronic conditions such as high blood pressure, diabetes and depression. Furthermore, magnesium can be found in some foods like leafy greens, nuts, seeds, avocados and whole grains — making it easy to incorporate into your diet!

Benefits of Recycling Magnesium

Recycling magnesium has numerous environmental, economic, and social benefits:

Recycling magnesium reduces the need for primary extraction, an energy-intensive and resource-depleting process. According to the International Magnesium Association, recycling 1 kg of magnesium saves 5.8 kWh of energy.

Recycling magnesium generates less waste, which helps to reduce pollution and protect natural ecosystems.

Recycling magnesium creates job opportunities in the recycling industry and can help to strengthen local economies.

How to Recycle Magnesium

Recycling magnesium usually involves melting scrap or discarded magnesium alloys and then purifying them to remove impurities such as zinc and aluminium. There are two main ways of recycling magnesium: scrap- and alloy-based. Scrap-based recycling involves melting down magnesium scrap without any other metal to create pure magnesium. Alloy-based recycling involves melting alloyed magnesium with other metals, such as aluminium or zinc, to create a new alloy.

Best practices for ensuring the highest quality recycled magnesium.

Producing high-quality recycled magnesium requires careful attention to detail and strict adherence to best practices:

The purity of the magnesium being recycled is crucial, as even small amounts of contamination can significantly affect the quality of the final product.

The right equipment, such as furnaces and crucibles, is essential to ensure the right conditions for melting and purifying the magnesium.

Regular testing and certification of recycled magnesium can ensure the quality and meet industry standards.


Recycling magnesium is vital to sustainable metal manufacturing with numerous environmental, economic, and social benefits. To ensure the best quality of recycled magnesium, following best practices for melting, purifying, and testing the metal is crucial. By recycling magnesium, we can reduce the environmental impact of primary extraction, protect natural ecosystems, and strengthen local economies. Recycling magnesium is an excellent way to promote sustainable metal manufacturing practices and contribute to a greener future.
