What is Slag? - Definition from Corrosionpedia

2018-01-08· Slag is the silicon dioxide and metal oxide mixture left over as a by-product of extracting metal from its ore during the smelting process. Once the metal is smelted out of its ore, the ore appears to be glassy. This glassy appearance is caused by the formation of slag on the ore's surface during the smelting process.

Plasma gasification - Wikipedia

Plasma gasification is an extreme thermal process using plasma which converts organic matter into a syngas (synthesis gas) which is primarily made up of hydrogen and carbon monoxide. A plasma torch powered by an electric arc is used to ionize gas and catalyze organic matter into syngas, with slag remaining as a byproduct.

smelting | Definition & Facts | Britannica

In the smelting process a metal that is combined with oxygen —for example, iron oxide—is heated to a high temperature, and the oxide is caused to combine with the carbon in the fuel, escaping as carbon monoxide or carbon dioxide. Other impurities, collectively called gangue, are removed by adding a flux with which they combine to form a slag.
