The final product from nickel concentrate smelting by either route is a molten nickel sulfide enriched phase (matte) which typically contains 15–40% Ni, 20–40% Fe, and 20–25% S as well as Cu, Co and any PGMs (Crundwell et al. Citation 2011a).
Thermodynamic modeling was used to simulate copper smelting [10][11], lead smelting [12] and nickel smelting [13][14][15] in a number of studies and proved to be very successful.
Older nickel-smelting processes, such as blast or reverberatory furnaces, no longer are 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.
Flash smelting ( Finnish: Liekkisulatus, literally "flame-smelting") is a smelting process for sulfur -containing ores [1] including chalcopyrite. The process was developed by Outokumpu in Finland and first applied at the Harjavalta plant in 1949 for smelting copper ore. [2] [3] It has also been adapted for nickel and lead production.
Global nickel smelting activity rebounded in November, powered by gains in North America and Europe, while refined copper production dipped, data from satellite surveillance showed on Monday.
However, this $500 million investment to build a smelting plant in partnership with an Indonesian state-owned company fell through after only a year because of declining nickel pig iron (NPI) prices and outputs. 11 Similarly, other investments—including IMIP, in collaboration with Bintang Delapan, a large Indonesian …
The conventional smelting and refining of Ni sulfide concentrates is an effective strategy for extracting Ni from sulfide ores. However, during the smelting process, sulfur is oxidized to sulfur dioxide (SO 2), which poses a significant environmental hazard.The present work investigates the feasibility of an alternative process to recover …
