Extraction Process of Cobalt

When it comes to the extraction process of cobalt, it’s primarily mined alongside copper and nickel. Cobalt ores are typically found in regions with significant mineral deposits, notably in countries like the Democratic Republic of Congo, Russia, and Australia.

Mining Methods

  • Open-pit mining: Involves extracting cobalt from large open pits using heavy machinery.
  • Underground mining: Involves tunneling underground to access cobalt deposits located deeper within the Earth’s crust.

Refinement Process

  • After extraction, cobalt ores undergo a series of processes to remove impurities and obtain high-purity cobalt.
  • Hydrometallurgical techniques are commonly used to separate cobalt from other metals and compounds present in the ore.

Sustainability Considerations

  • Sustainable cobalt mining is increasingly prioritized to ensure ethical sourcing and reduce environmental impacts.
  • Initiatives such as the Cobalt Refinery Supply Chain Due Diligence Standard aim to promote responsible cobalt sourcing practices.

Global Supply Chain

  • Cobalt extracted from mines is further refined and processed into cobalt metal or compounds for use in various applications, including electric car batteries.
  • With the rising demand for electric vehicles, ensuring a stable and ethical cobalt supply chain is essential to support the transition to sustainable transportation solutions.

Nickel Mining for Batteries

When it comes to the materials used in electric car batteries, nickel plays a crucial role alongside cobalt. Let’s delve into how nickel mining contributes to the production of these essential components.

Mining Process

  • Nickel is primarily extracted through both open-pit and underground mining, much like cobalt.
  • Open-pit mining involves removing layers of the earth’s surface to access the ore below.
  • On the other hand, underground mining requires digging tunnels to reach the nickel deposits located deeper underground.

  • Indonesia, in particular, is known for its large reserves of nickel ore, making it a prominent source for this vital material.
  • Nickel is a critical component in lithium-ion batteries, known for its role in enhancing energy density and overall battery performance.
  • Its use in electric vehicle batteries continues to grow as the demand for sustainable transportation solutions rises.

Remember, sustainable and ethical sourcing practices play a pivotal role in ensuring a responsible supply chain for nickel used in electric car batteries.

Aluminum and Copper Suppliers

So, where do aluminum and copper, two essential materials for electric car batteries, come from? Let’s dive in.

  • Aluminum:
  • Primary Source: Aluminum primarily comes from bauxite ore, which is mined in countries like Australia, Guinea, and China.
  • Processing: Bauxite is refined to extract alumina through the Bayer process. Alumina is then smelted to produce aluminum.
  • Key Suppliers: Major aluminum producers include China Hongqiao, United Company RUSAL, and Alcoa Corporation.
  • Copper:
  • Primary Source: Copper is mainly produced from sulfide ores through mining operations in countries such as Chile, Peru, and China.
  • Refining: After mining, copper ore undergoes processes like crushing, grinding, and flotation to produce copper concentrates.
  • Leading Suppliers: Top copper producers globally are Codelco, Freeport-McMoRan, and Glencore.

Understanding where these vital materials originate from sheds light on the intricate supply chain of electric car batteries.


You now have a clearer picture of where the essential materials for electric car batteries come from. Aluminum sourced from bauxite ore and copper extracted from sulfide ores play crucial roles in the production of these batteries.
