smelting process britannica

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.

Roasting, smelting, and converting - britannica

2019-10-30  Copper processing - Copper processing - Roasting, smelting, and converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace of either the hearth or

Aluminum processing - Smelting Britannica

Aluminum processing - Aluminum processing - Smelting: Although there are several methods of producing aluminum, only one is used commercially. The Deville process, which involves direct reaction of metallic sodium with aluminum chloride, was the basis of aluminum production in the late 19th century, but it has been abandoned in favour of the more economical electrolytic process.

Metallurgy - Matte smelting Britannica

2019-10-29  Metallurgy - Metallurgy - Matte smelting: The primary purpose of matte smelting is to melt and recombine the charge into a homogeneous matte of metallic copper, nickel, cobalt, and iron sulfides and to give an iron and silicon oxide slag. It is done in many types of furnace on both roasted or unroasted sulfide feed material. The reverberatory furnace is essentially a rectangular refractory

Hand tool - Smelting Britannica

Hand tool - Hand tool - Smelting: Perhaps 1,000 years after humans learned about melting virgin copper, they found that still another stone, a brittle one directly useless for tools, would produce liquid copper if sufficiently heated while in contact with charcoal. This step was epoch making, for it was the discovery of smelting, or the separation of a metal from a chemical compound called ore.

metallurgy Smelting - Students Britannica Kids

metallurgy - Smelting - Smelting is a process that liberates the metallic element from its compound as an impure molten metal and separates it from the waste rock part of the charge, which becomes a molten slag. There are two types of smelting, reduction smelting and matte smelting. In reduction smelting, both the metallic charge fed into the smelter and the slag formed from the process are

How Gold Is Recycled Sciencing

Once the gold is sorted, it will be melted in a crucible at around 1,064 degrees Celsius (1,947 degrees Fahrenheit) and either poured into bars marked by purity, or further smelted to remove impurities. Smelting is a process where impurities are burned off, or a flux is added to react with impurities and separate them from the pure metal.
