Smelting in chemistry
WebThe bath smelting process is a process of reducing iron oxides into liquid metal in a high-temperature vessel without using coking coal as fuel. The process’s advantages are environmental protection, fast reduction, and a good separation effect of slag and iron. WebWhile iron can be removed using a magnet, further smelting or chemical treatment could be required for the other metals. Magnetic moves. The magnets in phones require a different recycling approach. ... Victoria Atkinson looks at the clever chemistry that turns trees into sheets.
