2. Crucible - Wikipedia

   en.wikipedia.org/wiki/Crucible

   A modern crucible used in the production of silicon ingots via the Czochralski process Smaller clay graphite crucibles for copper alloy melting. A crucible is a container in which metals or other substances may be melted or subjected to very high temperatures.

3. Refining (metallurgy) - Wikipedia

   en.wikipedia.org/wiki/Refining_(metallurgy)

   In one of the previous melting stages, lead was added. Gold and silver preferentially dissolved in this, thus providing a means of recovering these precious metals. To produce purer copper suitable for making copper plates or hollow-ware, further melting processes were undertaken, using charcoal as fuel. The repeated application of such fire ...

   This cylinder, referred to as an electrode is then put into a large cylindrical enclosed crucible and brought to a metallurgical vacuum (0.001–0.1 mmHg or 0.1–13.3 Pa). At the bottom of the crucible is a small amount of the alloy to be remelted, which the top electrode is brought close to prior to starting the melt.

7. Non-ferrous extractive metallurgy - Wikipedia

   en.wikipedia.org/wiki/Non-ferrous_extractive...

   The mining water contains copper salts in the form of copper sulfate CuSO 4. The iron then reacts with the copper, displacing it from the sulfate ions, causing the copper to precipitate onto the iron sheets, forming a "wet" powder. Finally, the precipitated copper is collected and refined further through the traditional smelting process.
