The most viable route to recover copper from sulphide phase is flotation using chemical reagents which previous researchers such as [2, 12, 27] further elaborates on using a two-stage flotation process to recover copper and get 80–87% with iron being further concentrated by a specified technique of molten slag added complex additives. The ...
In this study, an attempt was made to recover copper from AbuSwayel deposit. A reverse flotation technique was applied leading to flotation of the accompanying oxide and sulfide minerals and gath ering copper oxide minerals in the sink product. The results showed that the application of such tech nique is possible under the optimum flotation conditions. Studying the main factors …
Disseminated copper ores (porphyry copper, copper sandstones and vein ores) characterized by low content of pyrite sulfur and copper (0.4–2.0%), depending on the pyrite content, can be …
The dominant challenge of current copper beneficiation plants is the low recoverability of oxide copper-bearing minerals associated with sulfide type ones. Furthermore, applying commonly used conventional methodologies does not allow the interactional effects of critical parameters in the flotation processes to be investigated, which is mostly overlooked in …
A significant part of copper and molybdenum losses (about 15%) during copper–molybdenum ores beneficiation is associated with the middlings cycle where mineral fractions with a comparatively high content of valuable components and low floatability are accumulated [1], [2].Middlings fractions are considered as the most suitable product for the …
