Agitation Leaching Behavior of Copper–Cobalt Oxide Ores

Agitation leaching is a promising technology in hydrometallurgy for treating copper–cobalt oxide ores. In this work, the behavior of oxide ores containing around 2.3% Cu and 0.3% Co received from Congo was investigated for varying particle size, acidity, pulp density, temperature, leaching time, and reduction potential.

Bornite (Peacock) : Properties, Formation, Uses and Mining

Bornite, commonly referred to as “peacock ore,” is a captivating mineral known for its striking and iridescent appearance. This mineral, composed primarily of copper iron sulfide (Cu5FeS4), draws its nickname from the kaleidoscope of colors that adorn its surface, resembling the vibrant plumage of a peacock. Bornite’s hues range from deep Copper concentrates are widely used in smelting operations worldwide and typically consist of chalcopyrite (CuFeS 2) as the primary mineral, with chalcocite (Cu 2 S) and bornite (Cu 5 FeS 4) as secondary copper-bearing minerals.However, these concentrates often contain hazardous impurities, such as the fluorine ion, which can Advancements in Removing Fluorine from Copper Concentrate Mining

Bornite an overview ScienceDirect Topics

For example, chalcopyrite and bornite are easily depressed by lime and cyanide. This is mainly because the outer electrons of the copper atom are 3d 10, which is full, so copper atom has low reactivity. For iron atom, the outer electrons are 3d 6, which has an unoccupied orbital, so iron atom shows more reactivity.

Geological context, mineralization, and timing of the

The most common sulfides associated with bornite are chalcocite and digenite. Where chalcocite or digenite rims bornite, the bornite is typically the purple (i.e., copper-rich) variety (Fig. 16a). Bornite (especially the pink variety) also forms boundary contacts with paragenetically earlier sulfides such as sphalerite, galena, and chalcopyriteA thermodynamic and kinetic model is proposed to explain the formation of bornite, chalcopyrite, and magnetite during partial roasting of enargite-containing copper concentrates. The proposed mechanism involves solid–solid–gas and solid–gas reactions between chalcocite, pyrrhotite, gaseous sulfur, and oxygen. Bornite formation could be Thermodynamic and Kinetic Mechanisms of Bornite

Most Common Copper Minerals » Geology Science

Copper minerals can be broadly classified into sulfide minerals, oxide minerals, and native copper. The most common copper mineral is chalcopyrite, a sulfide mineral that contains about 34% copper by weight. Other important copper minerals include bornite, chalcocite, and malachite.
