  • Etching (microfabrication) - Wikipedia

    Etching is used in microfabrication to chemically remove layers from the surface of a wafer during manufacturing. Etching is a critically important process module, and every wafer undergoes many etching steps before it is complete. For many etch steps, part of the wafer is protected from the etchant by a "masking" material which resists etching.

  • Iron processing | Britannica

    Production seems to have started in the copper-producing regions of Anatolia and Persia, where the use of iron compounds as fluxes to assist in melting may have accidentally caused metallic iron to accumulate on the bottoms of copper smelting furnaces. When iron making was properly established, two types of furnace came into use.

  • Copper - Wikipedia

    The process of recycling copper is roughly the same as is used to extract copper but requires fewer steps. High-purity scrap copper is melted in a furnace and then reduced and cast into billets and ingots; lower-purity scrap is refined by electroplating in a bath of sulfuric acid. Alloys. Copper alloys are widely used in the production of coinage; seen here are two examples - post-1964

  • How is Copper Tubing Made? | Hunker

    The melted copper is deoxidized in order to remove possible defects during the casting process. From the melting pot it moves into a holding furnace to be poured into a casting pipe which will eventually become the tubing. Once it has cooled and solidified, a large machine called a piercing mandrel drills a hole in the copper, creating the inside of the tubing. Now that we have the basic shape
