Currently, the slags are sent to a milling and flotation plant for liberation and recovery of residual copper. The copper recoveries realized in the plant are much lower than expected and it has been postulated that some copper minerals may be occurring in forms that are more difficult to float like oxides or fine disseminations in the gangue ...

This project is a "Copper flotation" project with some Moly (<200ppm). The chosen scale-up was 2.5 while The Book calls for on copper 2.1X. Without have access to the complete metallurgical testwork data and results I'd say 2.5X was the extra chosen to factor in Moly recovery which The Book calls for 2.6X.

The copper recoveries realized in the plant are much lower than expected and it has been postulated that some copper minerals may be occurring in forms that are more difficult to float like oxides or fine disseminations in the gangue ...

The first campaign was carried out using an existing copper slag flotation circuit in the plant. During the second campaign (2017), a circuit for sulfide ore flotation with an additional columnar …

In this fitting, the grade of copper in the floatable material (G Max) is 34% (this grade is very close to the grade of copper in Chalcopyrite mineral), the grade of copper in the non-floating component is 0.072%, while b is 0.0000408, indicating that the rate at which floatable material is recovery to the concentrate by true flotation is over ...

configuration is sequential flotation, where copper bearing minerals are recovered to a saleable copper concentrate, followed by re-activation and flotation of the pyrite which is leached with …

Based on the plant monthly data, the average copper recovery in the cleaner circuit was generally between 75 to 82 per cent. During April 2014 when the average mill throughput was 125,000 …

of your flotation plant, from installation and commissioning services to modernizations and upgrades. ... technology enhances particle recovery in the flotation cell, while also reducing power consumption and the risk of sanding. 4. ... • 12.6% improvement in copper recovery 10. The need to process more finely disseminated and complex ore ...

The mass recovery of less than five microns slimes due to entrainment is high. Where there's recovery of the coarser is less than thirty eight plus thirty one micron fraction …

The results showed an increase in the flotation recovery of fine valuable minerals. Zinc (Zn) production was increased by between 1,100 and 1,500 t/a, while salable yearly silver (Ag) production ...

Flotation of Copper Ores. In most plants engaged in the flotation of ores containing copper-bearing sulphide minerals with or without pyrite, pine oil is employed as a frother with one of the xanthates or aerofloat reagents or a …

In flotation practices as the particle size becomes fine, e.g., p<20μm, the process efficiency declines markedly. When flotation of fine particles is necessary, one method to improve the recovery ...

In previous years, numerous methods have been developed on the recovery and utilization of valuable metals in copper smelting slags, which can be summarized as pyrometallurgy [26], hydrometallurgy [27] and flotation [28].Through pyrometallurgy of copper slags, the precipitation of suspended matte (Cu 2 S) droplets is promoted into the matte layer …

No cleaning is practised; the whole of the concentrate from both series of machines is filtered, reground in cyanide solution, and then treated by an agitation process in the cyanide section of the plant. A total recovery of more than 97% of the gold and silver is made by flotation, while the combined flotation-cyanidation process gives an ...
