Where this word comes from

From German Kobalt, formerly also Kobald, ‑olt, ‑old, ‑elt, ‑el, apparently the same word as Kobold (“goblin”), from Middle High German, which became also a Harz Mountains silver miners’ term for rock laced with arsenic and sulfur, so called because it degraded the ore and made the miners ill. Doublet of kobold.
