manganese dioxide used in smelting of gold ore «

Iron was made by smelting iron ore or heating the ore up to melting point. Iron pyrites, or fool's gold, cannot be used to make iron because of its high sulphur Sintering drives off impurities, such as water, carbon dioxide, sulphur dioxide and arsenic compounds. Then an alloy of iron, manganese and carbon, is added.

How to Choose Gold Smelting Flux - Superb

Smelting is an integral part of the refining process of gold and other precious metals. It is the major part of refining where the precious metal (gold in this case) is melted out of its ore. Metal ores often contain a lot of other elements and impurities, smelting is therefore important in removing these.

Smelting - Wikipedia

Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.
