Copper Flotation - Mineral Processing & Metallurgy

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. The flow sheet depends on the mode of occurrence of the mineral ...

Method for achieving enhanced copper flotation …

05/05/1992· The new process results in a purer chalcopyrite concentrate than previously obtained in the presence of copper rimmed pyrite. The concentrate can be subjected to normal recovery processes, such as smelting. Due to the higher concentration of the copper in the concentrate, a higher percentage of pure copper can be recovered, rendering the smelting process more efficient and cost effective.

This approach could be implemented in froth flotation, the main process used to concentrate copper sulfide ores, by replacing the chemical reagents (i.e., collectors, frothers, and modifiers). These regents are used to control the particles’ superficial wettability and induce floatability over desired mineral selectivity ( Herrera-Urbina, 2003 ).
