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. ... 10-15% Soda Ash, and 5-1-% Silica sand. In most scenarios however, the properties of the ore will vary and so will require different proportions.
Iron processing - Smelting, Refining, Alloying: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron …
