![]() Tailings (left-over earth) containing copper oxide are routed to leaching tanks or are returned to the surrounding terrain. Minerals are concentrated into a slurry that is about 15% copper. Sulfide ores are moved to a concentrating stage, while oxide ores are routed to leaching tanks. The beginning for all copper is to mine sulfide and oxide ores through digging or blasting and then crushing it to walnut-sized pieces.Ĭrushed ore is ball or rod-milled in large, rotating, cylindrical machines until it becomes a powder usually containing less than 1 percent copper. Below is a quick description of the path. ![]() When it is recycled it can pass through some over and over again. It is therefore essential that, during shipping and transportation, they are not contaminated with any extraneous materials.Ĭopper Production from Ore to Finished Productįrom its original home buried underground in a mine to its use in a finished product such as wire or pipe, copper passes through a number of stages. Copper is also used in the production of brass, copper tube, copper sheet products, and found in over 450 alloys.Ĭopper cathodes are used as a raw material feed for the production of high purity copper and copper alloy products. Copper cathode is the primary raw material input for the production of copper rod for the wire and cable industry. It shows that Tesla is building strong relationships with some of the world’s biggest mining companies in order to secure long-term supply.Individual cathode sheets are manufactured to different dimensions by different suppliers in the range of 0,5 m 2 to 1 m 2 and 3 to 20 mm thick, with or without ‘ears’. This agreement reflects a shared commitment to sustainability and shows very clearly we are the supplier-of-choice for low-carbon and high purity nickel products essential for long-range batteries. We are pleased to have the leading electric vehicle manufacturer Tesla among our customers. This agreement is in line with our strategy to increase exposure to the electric vehicle industry, leveraging our low-carbon footprint and market-leading position as North America’s largest producer of finished nickel.ĭeshnee Naidoo, Vale’s Executive Vice President of Base Metals, added: Vale notes the disclosure by Tesla Inc today and confirms it signed a long-term contract with Tesla Inc to supply Class 1 nickel in the United States from its operations in Canada. Vale commented on its following Tesla’s disclosure today: The list confirms the supply relationship. Most of these suppliers were known to have a relationship with Tesla Vale has been rumored lately to have “ secret deals” for long-term nickel supply with Tesla. Tesla has been amongst the early automakers looking to build those relationships – on top of starting to build its own battery cells recently.įor the first time, Tesla released a list of all its “direct supplier relationships in the battery supply chain”: Supplier Generally, the miners and refiners deal with the battery cell manufacturers and not the automakers, but the latter started building direct relationships with miners of base metals in order to secure long-term contracts and ensure the flow of batteries years ahead. Several players in the industry have been raising the alarm that there are going to be massive shortages of some of the key materials. There’s currently a race to secure battery materials in order to support the rapid growth of the EV industry. Tesla has released a list of direct battery material suppliers and confirmed that it has a long-term nickel deal with Vale, the world’s largest nickel producer.
