Cobalt

What is Cobalt?

Cobalt is a chemical element with the symbol “Co” and atomic number 27. It is a hard, silver-gray metal that belongs to the transition metals and is known for its strong magnetic properties and corrosion resistance. Cobalt naturally occurs in minerals, often in combination with other metals like nickel and copper.

How is Cobalt extracted?

Cobalt is primarily extracted from ores that often contain nickel or copper, as it usually does not occur as a pure metal. The process begins with the mining of cobalt ores, which can take place in open-pit or underground mines. After mining, the ore is crushed and screened to separate the cobalt-bearing minerals. Chemical agents are then used to extract the cobalt from the minerals, employing special solutions that aid in the extraction process. Finally, the cobalt is purified and prepared for various applications, such as batteries or alloys. Major cobalt-producing countries include the Democratic Republic of the Congo (DRC), Russia, and Australia.

Ethics of Cobalt Extraction

In the DRC, many people work in hazardous conditions, often for low wages and without proper safety measures. Concerns over child labor and environmental damage are also prevalent. As a result, companies using cobalt, such as those producing batteries for electric vehicles, are under pressure to better monitor their raw material sources and ensure ethical standards.

To ensure compliance with ethical standards, EU guidelines like the EU Regulation on Critical Raw Materials require companies to monitor their supply chains and ensure that raw materials are sourced responsibly. Initiatives such as the Responsible Cobalt Initiative (RCI) and the Cobalt Refinery Supply Chain Due Diligence Standard support companies in meeting these standards. Metel adheres to these guidelines, ensuring that the cobalt they use is sourced in a sustainable and ethical manner. In this way, Metel contributes to both technological advancement and a fair and sustainable world.

Applications of Cobalt Alloys

Cobalt alloys are widely used in various sectors. These alloys are utilized in aerospace for engine parts and turbines. Additionally, cobalt is used in the production of tools and components exposed to extreme wear and corrosion, such as in the oil and gas industry and marine environments.

Another key area of application for cobalt is in the medical sector, where it is used in implants, prosthetics, and surgical instruments. Cobalt is also present in lithium-ion batteries.

Cobalt for Strong and Corrosion-Resistant Alloy Production

Cobalt is often used as an alloying element. It is typically combined with chromium and other metals to produce strong and corrosion-resistant alloys. These alloys play a significant role across various industries. In aerospace, they are used for components such as turbines and engine parts. They are also employed in the medical sector for implants and surgical instruments. In the oil and gas industry, they are utilized for valve seats and seals.
