After the air is brought up through the water, bubbles form that float the waterrepellent copper particles to the surface of the water. This separates out the froth which has 30% copper, 27% iron, and 33% sulfur. The flotation process gets rid of impurities in the ore, where there may also be lead and other vital metals in our society such as ...
