Currently, the supply chain from copper mining to copper wire production is . highly energy intensive. The smelting process requires pyrometallurgy to transform copper sulfides into sulfuric acid and a solid copper product (cathode). Oxidation removes molten iron (as FeO) and sulfur dioxide (SO. 2) gas from the ore. Several reactors upstream

This chapter briefly describes the technology for producing copper, from exploration, through mining and milling, to smelting and refining or solvent extraction and …

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 …

4. Beneficiation of Copper Ore. The next step in processing is called beneficiation. This is the first step in concentrating the copper into a more useable form. 5. Smelting and Extraction. The next step in the process flow is smelting for sulfide ore concentrate and solvent extraction for oxide ore leach solution.
