Even the best chemical method cannot remove all the impurities from the copper, but with electrolytic refining it is possible to produce 9999% pure copper (whatever method is used to manufacture copper from its ore, its final purification is by electrolysis) Process for the Electrolytic Refining of Copper Raw material: Blister Copper...
The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining In a few instances, however, leaching takes the place of concentrating, smelting, and refining At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated The milling of copper ores as practiced in the larger ....
• Rocks are crushed in a series of crushers Sulfide ores are further reduced through a ‘wet grinding’ process that ensures a particle size suitable for the flotation process Copper leaching Sulfide ores and froth flotation Sulfide ores are mixed with water and a surfacant creating a slurry...
The material that sinks in the first flotation cell goes on to two more flotation cells to recover as much copper as possible What doesn’t float is called tailings because it goes out the “tail end” of the flotation circuit About 80 percent of the water used in the milling process is reclaimed and re-used...
