The ore is comminuted and the cobalt rich oxides are separated by froth flotation. The cobalt-bearing concentrate is then mixed with lime and coal, and then melted in a reducing atmosphere. Iron and lighter impurities float to the surface as solid dross or are expelled from the melt as gas. The remaining liquid is composed of a heavier copper smelt containing approximately 5% cobalt that is processed for its copper and a lighter slag that is approximately 40% cobalt that is further r

Cobalt ore processing. The most important sulfide sources, the copper-cobalt ores of Congo (Kinshasa) and Zambia, are processed in a conventional manner to produce a copper-cobalt concentrate. This is then treated by flotation to separate a cobalt-rich concentrate for treatment in the cobalt circuit. Separation flotation utilizes pneumatic and ...

2021.9.30 The mineral composition of copper–cobalt ores is more complex than that of copper sulfides, and it is also difficult to discard tailing efficiently in primary flotation for the fine-grained disseminated of ore. In this work, a mineral liberation analyzer (MLA) was employed to study the characteristics of minerals. As a significant mineralogical

2023.11.27 With few exceptions, cobalt ore is not usually mined for the cobalt content. Rather, it is often recovered as a by-product from the mining of ores of iron, nickel, copper, silver, manganese, zinc, and arsenic, which contain traces of cobalt. Complex processing is required to concentrate and extract cobalt from these ores.
