Geometallurgy of cobalt ores: A review ScienceDirect
Cobalt is a fairly common element in Earth’s crust, averaging about 17.3 ppm (Rudnick and Gao, 2013), which ranks it as element no. 33 in terms of crustal abundance (Cobalt Development Institute, 2016a).Cobalt is found in relatively high concentrations in mafic and ultramafic igneous rocks (Table 1).The Ni/Co ratio decreases Abstract and Figures. Cobalt (Co) is a transition metal featuring unique physical properties which makes its use critical for many high-tech applications such as high strength materials, magnets(PDF) Geometallurgy of cobalt ores: A review

Lufilian copper–gold mineralization in the Mkushi District, Zambia
In Zambia, deposits of the Central African Copperbelt occur throughout the lower and middle parts of the Katangan sequence, although the classic copper–cobalt mineralization is hosted by the Copperbelt Orebody Member (Ore Shale) in the lower part of the stratigraphy, comprising 5–20-m-thick, strike-extensive, stratiform bodies (Selley et alThere are mainly four types of cobalt ores in the world. (1) Copper-cobalt ores, with the largest reserves in Congo (DRC) and Zambia. The cobalt production of Congo (DRC) accounts for more than half of the world’s output; (2) nickel-cobalt ores including sulfide ore and oxide ore; (3) smaltites; and (4) cobalt-containing pyrite.Cobalt Metallurgy SpringerLink

Cobalt Element information, properties and uses Periodic
Important ore deposits are found in DR Congo, Canada, Australia, Zambia and Brazil. Most cobalt is formed as a by-product of nickel refining. A huge reserve of several transition metals (including cobalt) can be found in strange nodules on the floors of the deepest oceans. The nodules are manganese minerals that take millions of years to formAn ammonia-based system was used to selectively leach cobalt (Co) from an African high-silicon low-grade Co ore, and the other elemental impurities were inhibited from leaching in this process. This process was simple and environmentally friendly. The results revealed that the leaching ratio of Co can reach up to 95.61% using Process and kinetics of the selective extraction of cobalt from

[PDF] Origin of the Nchanga copper–cobalt deposits of the Zambian
The Zambian Copperbelt forms the southeastern part of the 900-km-long Neoproterozoic Lufilian Arc and contains one of the world’s largest accumulations of sediment-hosted stratiform copper mineralization. The Nchanga deposit is one of the most significant ore systems in the Zambian Copperbelt and contains two major economic concentrations of Optimal flotation conditions were determined to be pH 6, a pH conditioning time of 7 min, and dosages of 50 g/t, 100 g/t, and 20 g/t of sodium hexametaphosphate, X-231, and DF250, respectively. According to the rougher flotation test results, a concentrate with a Co grade of 0.46% and a Co recovery of 84.15% was obtained.Investigation of Flotation Conditions for Cobalt Recovery
