Production of cobalt from copper-cobalt ores on the

Sep 01, 2020· A specific cobalt flotation circuit is run at KCM’s Nchanga concentrator. The ore from the Nchanga open pit contains pockets of ore with higher grades of cobalt, typically about 0.3% cobalt and 1.3% copper. This ore is processed in campaigns through the cobalt flotation circuit, which is illustrated schematically in Fig. 11. The concentrate

Continuous Flotation Testing To Recover Cobalt From

Mineralogical analyses showed the cobalt present as a distinct mineral phase, predominately siegenite, amenable to a physical separation method such as froth flota­ tion. Flotation was chosen for recovery because of easy adaptation by the mills. Unit processes of grinding, conditioning, and flotation were studied individually and in con­

Geometallurgy of cobalt ores: A review ScienceDirect

Jan 01, 2021· 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 ().The Ni/Co ratio decreases from ultramafic to acidic rocks because nickel enters the lattice of early
