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. The reducing agent is commonly a fossil fuel source of carbon, such as coke—or, in earlier times, charcoal. The oxygenin the ore binds to carbon at hi

Nickel processing - Extraction and refining Britannica

Nickel requires higher smelting temperatures (in the range of 1,350 °C [2,460 °F]) in order to produce an artificial nickel-iron sulfide known as matte, which contains 25 to 45 percent nickel. In the next step, iron in the matte is converted to an oxide, which combines with a silica flux to form a slag. This is done in a rotating converter of the type used in copper production. The slag is ...
