Melting is the process of changing a solid to a liquid using heat. Once this process is completed, the melted material cools and becomes a solid once again. Smelting, on the other hand, involves changing the chemical content of the material. When you smelt, you are "burning off" the other materials that your gold is currently mixed with ...
The pressure on the steel industry to reduce its carbon footprint has led to discussions to replace coke as the main reductant for iron ore and turn to natural gas, bio-syngas or hydrogen. Such a major transition from the blast furnace-basic oxygen furnace route, to the direct reduction-electric arc furnace route, for steel production would …
