Global flotation of copper–cobalt, from a pre-concentrate obtained by gravitational means. 2. ... If this is the case, additional fuel is required, usually in the form of coal or sulfur which is mixed with the ore and fed to the roaster using a screw feeder. Some other operations have experienced problems with sulfur simply as it sublimates ...

— 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 …
incoming ore down to a normal cleaner flotation feed density. This option, however, results in a slightly lower recovery efficiency of both copper and cobalt compared
The process involves two basic flotation methods: (a) fatty acid flotation of oxide copper minerals from siliceous ore, and (b) sulphidization of oxide copper minerals followed by …
— Flotation methods include direct flotation (using chelating reagents or a fatty acid as collector), sulfidization flotation (using xanthate as collector), and activation …

cobalt minerals, as most studies consider the flotation of cobalt ores as part of the main metal, such as copper and nickel [19]. Cobalt is an essential metal with a wide range of uses, and it is obtained from secondary sources in Turkey. The Küre deposits, known as the pyrite-containing copper deposit, are a significant source of cobalt.
— The flotation by surface sulphidisation of the oxidized copper-cobalt-bearing ore from Kimpe (1.97% Cu; 0.66% Co) was studied in order to evaluate its behavior by the analysis of its most ...
The role of ore mineralogy on the flotation performance of copper-cobalt sulphides was studied by tracking the changes in mineral properties with time throughout the flotation process. A series of laboratory rougher-scavenger flotation experiments were carried out using a dithiophosphate collector to define the optimum collector dosage, which ...
Three cobalt-bearing oxide minerals are observed in the mixed ore, i.e. heterogenite, kolwezite and cupro-asbolane, while carrollite is the only cobalt-bearing sulphide mineral. A two-stage rougher-scavenger flotation process is used in which sulphides are extracted from the ore first.
