Flotation is the main method of processing copper ores
Copper-porphyry ore deposits are the largest in terms of copper reserves. The largest copper processing plants with a capacity of up to 90 thousand tons of ore per day and more operate on their basis. Primary copper-porphyry ores mainly include molybdenite-chalcopyrite ores with a low content (2-5%) of pyrite.
