Environmental Impact of Flotation Processing

Environmental Impact of Flotation Processing . Valuable minerals in an ore can be separated from each other, and from worthless minerals, by the froth flotation process. The need for a process to extract ore arose from major sulfide mineralization after the oxide ores had been depleted.
