Nickel: smelting, producing-Metalpedia

Flash smelting. Flash smelting (Finnish: Liekkisulatus) is a smelting process for sulfur-containing ores including chalcopyrite. The process was developed by Outokumpu in Finland and first applied at the Harjavalta plant in 1949 for smelting copper ore. It has also been adapted for nickel

What Is Nickel Smelting? (with picture) - Info Bloom

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 ...
