The most …
The fundamental basis for this alternate process is the thermodynamics of Fe–Ni–S system, showing that iron can substitute nickel in (Fe,Ni) x S y, resulting in the precipitation of FeNi alloy. Fig. 1 depicts the Fe–Ni–S phase diagram at 950 °C, in which the Pn composition is marked by a solid square near the middle of the diagram. At this …
Primary world nickel production in 2020 was 2430.7 kt Ni; 69% (1677.7 kt) of them came from oxidized nickel ores (laterites) and 31% from sulfides. Production-wise, 87.7% of the 1677.7 kt came from pyrometallurgical and 12.3% from hydrometallurgical processes. For a long time, Fe-Ni had a 20–40% Ni analysis, but in 2006 a new Fe-Ni quality came into …
Nickel matte remains after the mining and processing of either lateritic or sulfidic ore. Using the fluid bed roasting procedure, a 95 percent pure nickel can be …
The technology treats the full laterite ore profile, namely limonite, saprolite, and the transition zone, in one continuous process and uses nitric acid to dissolve the metals into a solution.
Laterite ore is a valuable resource due to its high content of metals essential for modern technology, including nickel, iron, and cobalt. However, extracting nickel from laterite ores is challenging due to their complex mineral composition and low nickel concentrations. This study examined the leaching behavior of pre-roasted laterite ore …
