Prediction and Optimisation of Copper Recovery in the Rougher Flotation
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 …
Copper processing
For lower-grade deposits located near the surface, the open-pit method is the most practical for the mining of large tonnages of material. Large track-mounted drills prepare the ore for blasting, and the broken ore is hauled to the ore-dressing plant by truck (at up to 150 tons per load) or conveyor. In underground mining, vertical shafts are sunk well over 1,000 …

Design Flotation Plant
Thickening and filter capacity is selected for a 10 to 1 ratio of concentration as would be the case when treating a 3% copper ore with the copper mineral being chalcopyrite. In such case it would be necessary to filter 50 to 55 tons of concentrates each day. The use of a mineral jig or flotation unit cell in the grinding circuit is recommended.

1 Froth Flotation – Fundamental Principles
no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.
