  Advanced study on the extraction of Nickel from its ores

  2024612 · The mined ores (1–4% Ni) are processed to upgrade the metal content with 10–20% Ni in the concentrates. Thus, the preconcentration of nickel ores is an important unit operation to upgrade the nickel before commencing any extraction steps. Ni is mined from sulfide ores, Nickel ferrolaterite and serpentine.

  Nickel Smelting And Refining Industry - Environmental XPRT

  199811 · Older nickel-smelting processes, such as blast or reverberatory furnaces, are no longer acceptable because of low energy efficiencies and environmental concerns. In flash smelting, dry sulfide ore containing less than 1% moisture is fed to the furnace along with preheated air, oxygen-enriched air (30–40% oxygen), or pure oxygen.

  Recent Progress in Hydrometallurgical Processing of Nickel …

  2022822 · The main products obtained through the pyrometallurgical route are Nickel matte and ferronickel. Pyrometallurgical routes mainly include drying, calcining/reduction, electric arc furnace smelting, and refining . Matte smelting and smelting to ferronickel are energy-intensive, making it uneconomical to treat low-grade ore.

  Sulfide Smelting - Physical Chemistry of Metallurgical …

  2016210 · Smelting happens to be one of the main steps in the extraction of metals from sulfide and oxide minerals by adopting the pyrometallurgical route. During smelting, constituents present in the charge in molten state separate into two immiscible liquid layers, namely, liquid matte or metal and liquid slag. The primary objective of matte smelting ...

  Teck's CESL Nickel Process: Advancing Towards a …

  2021112 · Smelting and refining of massive sulphides begins with the flotation of ore, typically in the range of 0.2-2% nickel, to an acceptable concentrate grade of 10 to 20% nickel. Concentrate smelting produces a high grade nickel matte which is then refined hydrometallurgically. With the majority of
