Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered …

The demand for copper is ever-increasing, playing a critical role in the transition to a clean-energy economy. By the early 21st century, most of the rich copper oxide ores had already been mined out, leaving current deposits with a grade sometimes less than the tailings of earlier mining [1,2].A study conducted by Calvo et al. [] revealed …

One kilogram of ore, at -200 mesh was used as feed to the bulk flotation that was conducted for 8 minutes. Two collectors, independently added, were used at 3 different dosages: 20, 30, and 40 g/ton. The copper and …

Furthermore, Sahyoun et al. (2005) conducted flotation tests on the same ore and demonstrated a 3–6% increase in copper recovery after microwave treatment (up to 12 kW and 1.7 kW h/t on <22 mm size material) as opposed to the 1% increase reported by Kingman et al. (2000a), attributed to the higher power density sustained in the single …

The recovery of these copper minerals by flotation or hydrometallurgy from ores, typically containing 0.5%TCu (open pit …

As shown in Table 3, S-7261A exhibits good selectivity in copper-arsenic flotation. Despite the changing ore properties in the regulation process, such as the varying content of secondary copper sulfide and copper oxide, excellent flotation index is still obtained with S-7261A as the depressant.

Flowsheet for treatment of Copper Sulfide ores rich inminerals such as chalcopyrite with gold and silver as well as arsenopyrite. The above flowsheet is designed for the treatment by flotation of …

The flotation behavior of mixed copper ore during selective copper flotation was investigated using a geometallurgical approach. To this end, samples were taken from a production block at the Ouansimi copper deposit and subjected to laboratory batch kinetics tests and quantitative mineral analyses.

Copper sulphide ore deposits are of great economic significance for copper extraction. In order to enrich copper sulphides, froth flotation at alkaline pH is typically applied to reject associated gangue minerals, in particular pyrite before the subsequent pyrometallurgical treatment to extract copper from copper sulphides [].The selective …

porphyry copper ore per year (at a grade of 0.4% cop-per), applies the bulk-differential flowsheet and pro-duces copper and molybdenum concentrates.
