Rising bubbles carry the copper minerals up and over the edge of the flotation tank. The bubbles break soon after they flow over the edge. The copper minerals are then ground up even finer and purified by another flotation process. The dried copper concentrate of about 28 percent copper is shipped to the smelter. It representsless than one percent of the material removed from the mine.
