Copper is very well suited to being recycled because it can be remelted endlessly with no loss of properties. For example, old copper plumbing pipes, taps and car radiators are a major source of recycled copper. They can all be melted down and made into new products. Even the few grams of copper in your mobile phone is worth recovering.

How is copper mined and processed? Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. After the ore is crushed, it''s roasted, which helps to convert sulfides to oxides. The oxides are smelted to produce matte, which then undergoes several refining processes.

Copper mining is usually performed using Following mining, transporting, and crushing to a consistent gravel or golf ball-size, the crushed ore is further processed at a mill using secondary crushers, and reduced to pebbles, and finally to fine sand. Using today’s compact mining equipment, copper ore is extracted from the mine.After the ore is crushed, it’s roasted, which helps to

Copper oxides are more abundant near the surface, but are considered low-grade ore, with a lower concentration of copper. Although this requires more ore to be extracted and processed, this process is less expensive, so oxides can still be mined at a profit. On the other hand, while copper sulfide ores are less abundant, they contain higher

The remaining mixture is a molten copper sulfide referred to as matte. The next step in the refining process is to oxidize liquid matte in order to remove iron to burn off sulfide content as sulfur dioxide. The result is 97-99%, blister copper. The term blister copper comes from the bubbles produced by sulfur dioxide on the surface of the copper.

Electroplating is mainly done for avoiding corrosion of metals and for decorative purposes. Electroplating is a widely used process in many industries like automobiles, airplanes, electronics, jewelry, toys and many more. Electroplating is conducted in an electrolytic cell. The metal to be electroplated is connected to the cathode.

Apr 09, 2010· Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace. Molten copper is poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of 99.9% purity. Copper can be recycled indefinitely without the base metal

For example, if the top copper layer is to have a finished copper weight of 2oz, then the bottom layer should also be 2oz. If a different copper weight is specified for top and bottom, say 2oz on top and 1oz on bottom, then the amount of time required to etch through the top side copper will be longer than needed for the bottom. This would result in over etching the bottom layer. Each side
