Flotation of nonsulfide copper minerals is rare because these ores are mostly subjected to hydrometallurgical copper recovery for example heap leaching In Zambia and Zaire however siliceous copper oxide ores are floated with fatty acid collectors and dolomitic copper oxide ores are sulfidized with sodium hydrogensulfide and then floated.
