evaluation of mineral and water chemistry which can affect the flotation process and completion of adequate metallurgical and process testwork to allow the design of flowsheet reagent scheme and process control requirements In order to illustrate the generic factors involved both in evaluating flotation flowsheets and

The production of concentrates implies the crushing and later milling of the ore down to a particle size allows releasing copper by flotation The concentrates from different regions have approximately between 24 up to 36 of copper Copper concentrates are then submitted to a final filtration and drying process to decrease the humidity to 8 9

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

Toowong Process has demonstrated that it is an option for removing impurities from dirty copper concentrates Albion Process has a role in improving overall project economics by improving recovery of copper from certain more difficult projects along with dealing with impurities
