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. Noncopper minerals do not attach to the rising bubbles; they are discarded as “tailings.”
