Cobalt - an overview | ScienceDirect Topics



Cobalt (but not nickel) also occurs in the copper– cobalt oxide ores from the Central African Copperbelt. These ores typically contain about 3% Cu and 0.3% Co. The main cobalt mineral is heterogenite [CoOOH]. Copper occurs as chrysocolla [CuOSiO 2 ·2H 2 O] and malachite [CuCO 3 ·Cu(OH) 2]. Some sulphide ores are also mined.

Cobalt - Wikipedia



The word cobalt is derived from the German kobalt, from kobold meaning "goblin", a superstitious term used for the ore of cobalt by miners. The first attempts to smelt those ores for copper or nickel failed, yielding simply powder (cobalt(II) oxide) instead.
