  • Nickel - Wikipedia

    Smelting. It is a form of extractive metallurgy. It is used to extract many metals from their ores, including silver, iron, copper, and other base metals. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

  • Nickel Flash Smelting :: Total Materia Article

    Any materials resulting as smelting and converting slags are recirculated in the electric furnace and recovered where possible as nickel matte. Nickel (Ni) is a silvery-white, hard metal. Although it forms compounds in several oxidation states, the divalent ion seems to be the most important for both organic and inorganic substances, but the trivalent form may be generated by redox reactions in the cell.

  • Flash smelting - Wikipedia

    Flash smelting (Finnish: Liekkisulatus, literally "flame-smeling") 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)

    Oct 18, 2019· 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 contain nickel; and sulfidic ore, which is mined from underground.

  • Nickel processing - Extraction and refining | Britannica.com

    Nickel requires higher smelting temperatures (in the range of 1,350 °C [2,460 °F]) in order to produce an artificial nickel-iron sulfide known as matte, which contains 25 to 45 percent nickel. In the next step, iron in the matte is converted to an oxide, which combines with a silica flux to form a slag.
