Smelting - WikipediaSmelting is a form of extractive metallurgy; its main use is to produce a base metal from its ore. This includes production of silver, iron, copper and other base metals from their ores. Smelting makes use of heat and a chemical reducing agent to decompose.smelting reduction use,Energy consumption in smelting reduction (SR) processes - SciELOThere are several direct reduction devices that can be used for smelting reduction. The shaft and fluidized bed are the most practical and are usually selected by.
The purpose of smelting reduction is to produce liquid hot metal. It. requires little preparation of iron ore and uses coal, oxygen, and/or electrical energy. Details.
