Nickel matte is a semi-finished product created during the extraction of nickel from its ores. It typically contains about 25-45% nickel, along with other metals like copper and iron. The production process involves smelting, where the ore is heated to separate the metal from impurities. This material is an important intermediate in the production of pure nickel. After obtaining nickel matte, further refining processes, such as electrolysis or pyrometallurgy, are used to extract pure nickel for various applications, including batteries, alloys, and industrial processes.
