year, Kodama et al. [] reported the smelting of iron sand 7 in a small blast furnace and concluded that it was dicult to smelt iron sand only in a furnace because of the high vis-cosity of molten pig iron, unless the iron sand is mixed with other iron oxide source at 1:1 ratio. * Imam Santoso [email protected]

Microwave smelting is used for many different metals and alloys, including silver, gold, copper, and aluminum. The process can also be used to create pure ceramics from raw materials such as silicon dioxide (sand). The basic idea behind microwave smelting is that metal ores contain many different elements that have different melting points.

Smelting is a method of obtaining refined goods from raw materials by heating in a furnace, blast furnace, smoker or campfire. For example, raw iron can be smelted to produce iron ingots using coal as fuel. Like crafting, smelting uses recipes to determine what item is produced, but its recipes are simpler. Smelting also yields experience. The furnace, …
