Nickel: smelting, producing-Metalpedia

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 and lead production.

Nickel isotope fractionation during laterite Ni ore

2016-1-1  The smelting slags are isotopically heavier (δ 60 Ni = 0.11–0.27‰, with an average of 0.18 ± 0.05‰, n = 8) than FeNi (0.04–0.07‰), highlighting that Ni fractionation occurs during the reduction of Ni II O. Similar heavy isotopic enrichment has been observed in smelting and refining Zn smelting slags (Sonke et al., 2008, Shiel et al., 2010, Bigalke et al., 2010), and Pb–Zn smelting slags, for Cd isotopes
