Turning Copper Ore into Copper: What are the Processes?
After the air is brought up through the water, bubbles form that float the water-repellent 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 …
