separation of copper ores

Methods Used To Separate Copper Ore From Other

Separation of special copper ores such as those containing molybdenite or with high zinc or lead content Canada is also possible by flotation methods. Flotation of non-sulfide copper minerals is rare because these ores are mostly subjected to hydrometallurgical copper

Copper extraction - Wikipedia

Most copper ores contain only a small percentage of copper. The remainder of the ore consists of gangue of no commercial value. Gangue from copper mining typically contains silicate mineralsand oxides. In some cases these tailings have been retreated as the for recovering copper has improved. The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals (including copper) being less than 2% of the total volume of the ore rock. A key
