Environmental Impacts of Nickel Mining and Processing ...

Nickel deposits are typically found in low-grade ores (~1-2% nickel) thus making it highly energy intensive to extract and refine the metal. This leads to high emissions of greenhouse gases into the atmosphere and the use of large amounts of energy derived predominantly from fossil fuels ( 2 ).

What Is Nickel Smelting? (with picture)

Alex Newth Nickel ore must melt until it becomes a product known as liquid matte, which is usually around 45 percent nickel. Nickel smelting is the process that nickel ore goes through to eventually remove impurities and leave just the nickel metal. While the ores can come from different stones and sources, they have two categories: lateritic, or rocks found in tropical climates and which ...
