Smelting is a process used to extract valuable metals from ore. It involves heating the ore to a high temperature, usually with a fuel such as coal, and then fusing it with a flux such as limestone. This causes the ore to MELT and separate from the impurities, which can then be refined further. The end product of smelting is often a metal such as gold or silver, but it can also produce other materials such as ROE or capelin. STANK is an archaic term for the smell of burning ore during the smelting process.
