- - - - ABS is most commonly polymerized through the process of emulsion (the mixture of multiple products that don't typically combine into a single product). A well-known example of an emulsified product is milk.
  - - - Polyamides are typically made by combining two monomers namely, adipic acid with 1,6-diaminohexane. Once these two monomers have reacted together they form water as a by-product of each polymer chain linkage. This linking of the two monomers is known as polymerisation.
  - - - The manufacturing method of PLA is the ring-opening polymerization of the dimeric cyclic ester of lactic acid, lactide. For the stereocomplex PLA, we developed the four unit processes, fermentation, separation, lactide conversion, and polymerization.
- - - - Image result for stainless steel manufacturing process
        Stainless steel metal is formed when the raw materials of nickel, iron ore, chromium, silicon, molybdenum, and others, are melted together. Stainless steel metal contains a variety of basic chemical elements that, when fused together, create a powerful alloy.
  - - - Silver is commonly extracted from the powdered ore by smelting or chemical leaching. ... This separates the silver and gold. Silver is also produced during the electrolytic refining of copper and by application of the Parkes process on lead metal obtained from lead ores that contain small amounts of silver.

        The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold..
  - - - Aluminium is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen
        
        Aluminum is manufactured in two phases: the Bayer process of refining the bauxite ore to obtain aluminum oxide, and the Hall-Heroult process of smelting the aluminum oxide to release pure aluminum
