Copper Flotation - 911 Metallurgist

May 16, 2016  The flotation of native copper ores is nearly always preceded by gravity concentration in jigs and tables not only because the combined process is more economical as regards costs, but also because the copper often occurs as large grains which flatten out during grinding and cannot be broken to a size small enough for flotation.

Copper Sulfide Flotation - 911 Metallurgist

Apr 13, 2016  Standard “Sub-A” Flotation Machines are used for both the rougher and cleaner circuits, where their cell-to-cell principle gives both high recovery and a good grade of concentrate. The rougher concentration is accomplished in 6 or 8-cell flotation machines, with the concentrate from each going to a separate bank for cleaning and re-cleaning.

1 Froth Flotation – Fundamental Principles

This tells us that the concentrate has 9.57 times the copper concentration of the feed. 1.1.1 Grade/Recovery Curves While each of these single calculated values are useful for comparing flotation performance for different conditions, it is most useful to consider both the grade and the recovery simultaneously, using a “Grade/Recovery Curve”.

Concentrating - Resolution Copper

Concentrating. In the second step of the production process, we convert the ore from a low-grade material into a concentrate of high-grade copper inside the Concentrator Complex. The technique all begins with a wet grinding process that turns the crushed ore into a slurry and transports it to flotation cells.

Froth flotation cells to concentrate copper and nickel sulfide minerals, Falconbridge, Ontario. Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity. Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and ...
