What Is Silver Smelting? (with pictures) - wiseGEEK

Feb 14, 2020· Smelting is a method of melting ore, which is rock containing valuable metals, to purify out the contents. Silver smelting to extract pure silver from lead- and copper-based ores has been a practice since at least 2,000 BC.The metal was discovered in its natural state and used for jewelry as early as 4,000 BC.

What is Slag? (with pictures)

Oct 01, 2019· Non-ferrous smelting, used to refine copper, lead, and similar metals, produces highly ferrous slag, as iron is an undesired element. Ferrous smelting, such as that used to produce steel, creates non ferrous slag, as all the iron is used in the smelting process. After slag is allowed to age, it can be sold for use in other industrial processes.

Slag: From Metals By-product to Valuable Construction Material

Slag is a by-product of the metallurgical smelting process. Slag has a double role: it permits removal of impurities, known as gangue, from the melt by forming oxides. It also allows exchange reactions with the liquid metal, permitting control of the process in order for the desirable elements to stay in the melt while the others are removed.
