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%.

Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.

Crushing is typically a dry operation that is performed in two- or three-stages (i.e., primary, secondary, tertiary crushing). Lumps of run-of-mine ore as large as 1.5 m across are reduced in the primary crushing stage to 10–20 cm in heavy-duty machines. In most operations, the primary crushing schedule is the same as the mining schedule.
