Puddling (metallurgy) - Wikipedia
The process begins by preparing the puddling furnace. This involves bringing the furnace to a low temperature and then fettling it. Fettling is the process of painting the grate and walls around it with iron oxides, typically hematite; this acts as a protective coating keeping the melted metal from burning through the furnace. Sometimes finely pounded cinder was used instead of

To make a good sword, the carburizing, hammering, and carburizing processes had to be repeated about 20 times before the steel was finally quenched and tempered and made ready for service.
Why Iron Rusts (And How to Prevent It) - Monroe,
Oct 24, 2019· Galvanization, for example, is a common anti-corrosion treatment process for iron. It involves the application of a protective coating over the surface of a metal workpiece. With galvanization, zinc is applied over the surface of iron. The zinc layer acts as a barrier between the iron and its surrounding environment. As a result, the iron doesn,
Innovations: How Hydrometallurgy and the SX/EW Process,
The SX/EW Process has its roots in analytical chemistry where it is used to separate one metallic ion from another. It was first used as a large-scale process during World War II for the recovery of uranium from its ores. The key to the process is the development of organic extractants that are specific to the metal to be extracted.
