The intelligent decision-making of copper flotation backbone process
2022年5月11日 To draw the flotation backbone flow chart of copper mine, we need to complete three decision-making tasks: product scheme, flotation scheme and grinding scheme. The product scheme determines which kinds of concentrates are extracted from the raw ore as products in addition to copper concentrate.

1 Froth Flotation – Fundamental Principles
Table 1: Grade/recovery performance of a hypothetical copper ore flotation process. Product % Weight % Cu Assay Feed 100 2.09 Concentrate 10 20.0 Tailings 90 0.1 (a) From Table 1, the Ratio of Concentration can be calculated as F/C = 100/10 = 10. If only assays are available, the ratio of concentration equals (20 – 0.1)/(2.09 – 0.1) = 10 ...

The Recovery of Copper from Smelting Slag by Flotation Process
2017年2月8日 Flotation Results. Figure 2 shows the effect of grinding fineness on recovery rate of copper. It is observed that a rise of the proportion of the grinding fineness of −0.074 mm from 60 to 80% obviously increased the copper recovery , then decreased when it exceeded 80%. This is because the initial appearance was dissociation fragmentation ...

Copper recovery from copper slags through flotation
2022年6月1日 Copper is made from copper ores through concentration, smelting and refining. The ores are concentrated through froth flotation in the form of copper-sulfide or copper-iron-sulfide minerals (e.g. chalcopyrite, chalcocite and etc.), which are then melted in a high-temperature reheating furnace (± 1250 ℃).
