metal - Extraction of nickel from its ores - Chemistry Stack Exchange

Nickel can be extracted directly from its ore by reduction by hydrogen or carbon monoxide at elevated temperature at 600 ∘ C to 650 ∘ C : N i O + H X 2 ⟶ N i + H X 2 O. N i O + C O ⟶ N i + C O X 2. Also, it can be extracted by treatment with dilute sulfuric acid following by precipitation: N i O + 2 H X + ⟶ N i X.

NICKEL

Saxon miners were familiar with the reddish-coloured ore NiAs (Nickel Arsenide) which resembles Cu2O (copper oxide). These miners attributed their inability to extract copper and the fact that the ore was making them ill was work of the devil and named the ore “Kupfernickel” (Old Nick's Copper), however it was the arsenic.
