Cobalt—Styles of Deposits and the Search for Primary Deposits

Cobalt (Co) is a potentially critical mineral. The vast majority of cobalt is a byproduct of copper and (or) nickel production. Cobalt is increasingly used in magnets and rechargeable batteries. More than 50 percent of primary cobalt production is from the Central African Copperbelt.

Cobalt Ores Article about Cobalt Ores by The Free Dictionary

The main minerals of the arsenic cobalt ores are compounds of cobalt, nickel, and iron with arsenic (arsenides) or with arsenic and sulfur (sulfoarsenides). The arsenides include skutterudite (up to 20 percent Co), complex mixtures of smaltite-chloanthite (from 1–5 to 20 percent Co), and safflorite-loellingite (traces to 23–28 percent Co).

Cobalt - Wikipedia

Cobalt is a chemical element with the symbol Co and atomic number 27. Like nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal. Cobalt-based blue pigments (cobalt blue) have been used since ancient times for je

Development of a Method for Cobalt Recovery from Cobalt Ore

May 30, 2019  Ore processing using sulfating roasting followed by leaching with water is proposed. The mechanism of sulfate formation, a sequence of the sulfation of the ore minerals at various temperatures, and the degree of recovery of the minerals are studied. The degree of recovery of cobalt reaches 85% for leaching of the ore sulfated at 700°C.

The ore was shown to contain high Fe and As concentrations and negligible Zn and Ni concentrations. Cobaltite (CoAsS) and erythrite (Co 3 (AsO 4) 2.8H 2 O) made up the two main cobalt‐bearing minerals in the ore. The washing processes that were conducted based on a historical text rendered the ore more enriched with erythrite.
