Beneficiation
1.1 Physical Beneficiation. Beneficiation of copper ores is done almost exclusively by selective froth flotation. Flotation entails first attaching fine copper mineral particles to bubbles rising through an ore–water pulp and, second, collecting the copper minerals at the top of the pulp as a briefly stable mineral–water–air froth.
