Froth Flotation Process

The ore is crushed in the copper froth flotation process in order to separate the copper minerals from the gangue minerals. After that, the resulting slurry is floated, a process in which air bubbles are added to the slurry and the copper particles cling to the bubbles, rising to the surface as froth. ... lead, zinc, and gold. What is flotation ...
