of xanthate flotation of the sulphide minerals, followed by acid leaching of the oxides. The traditional method applied for the flotation of copper oxide or mixed ores is sulphidization, which was first developed with industrial success on Pb-Zn oxide ores in Australia (Crozier, 1991). The method involves stage addition of sodium

Copper Concentrates - Cargo Handbook - the world's largest ...

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 ground ore will pass through a copper flotation circuit followed by a rougher concentrate regrind stage and two stages of cleaner flotation. The rougher flotation cells will produce a low-grade copper-molybdenum (Cu-Mo) concentrate, which will be pumped to a concentrate thickener via a trash screen.
