Cobalt production in the Copperbelt increased about 600% between 1990 and 2021, according to data from the U.S. Bureau of Mines and the U.S. Geological Survey. The vast majority of cobalt is produced as a byproduct of copper mining, though some copper mines do not produce any cobalt.

Copper cobalt oxides with cation ratios from 5:1 to 1:5 were investigated as conversion-type electrodes in lithium ion batteries. The synthesis of the materials was carried out via sol gel self-combustion synthesis to enable the production of nearly homogenous copper cobalt oxides with nanosized crystallites, independent from the …

Cobalt derived its name from German miners. They named cobalt ore after mischievous spirits called kobalds. Cobalt ores commonly contain the useful metals copper and nickel. The problem with cobalt ore is it usually contains arsenic as well. Attempts to smelt the copper and nickel typically failed and would often produce arsenic oxide gases.

The best sample, a mixed cobalt-copper oxide annealed at 500 °C, showed a stable nominal overpotential of -235 mV in the galvanostatic test and -40 mV at linear sweep voltammetry. The electroactive surface area for the sample was 688 cm 2 at an impedance of 3 Ohms. It was noted that the electrocatalytic features of the electrode …

Cobalt naturally occurs in nickel-bearing laterites and nickel-copper sulfide deposits and, thus, is most often extracted as a by-product of nickel and copper. According to the Cobalt Development Institute, about 48% of cobalt production originates from nickel ores, 37% from copper ores and 15% from primary cobalt production.
