cobalt and copper ore

Copper-Cobalt ores - DanafloatCopper-Cobalt ores. Various cobalt bearing minerals have economic significance including cobaltite (CoAsS). carrollite (Cu(Co.Ni)2S4), and linnaeite (Co3S4). These are often associated with copper minerals and pyrite and pyrrhotite iron sulphides. Two different flotation separation strategies are used. Differential flotation.cobalt and copper ore,cobalt and copper ore,Ores Containing Cobalt | Cobalt Institute formerly the Cobalt .Economic concentrations of cobalt can be found in four different geological settings, outlined in Table 2. Cobalt is almost always a by- or co-product of mining for other base metals, chiefly nickel and copper. Large quantities of cobalt also occur on the sea floor, contained within manganese nodules and cobalt-rich crusts,.

A distinction is made among arsenic,.

Cobalt - Wikipedia

Today, some types of cobalt are produced specifically from one of a number of metallic-lustered ores, such as for example cobaltite (CoAs S). The element is however more usually produced as a by-product of copper and nickel mining. The copper belt in the Democratic Republic of the Congo (DRC), Central African.

Distribution of copper, cobalt and nickel in ores and host-rocks .

Unusually high cobalt contents of metavolcanics and of sulphide minerals in orebodies suggest a consanguinity between ores and rocks. 90% of total nickel, 70% of total cobalt but only 30% of total copper in rocks occur in silicate phases and thus indicate an early separation of copper from cobalt and nickel. Unusually high.
