Produced Smelting Slag

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.

Slag - Wikipedia

Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore. Slag is usually a mixture of metal oxides and silicon dioxide. However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature controlof the smelting, and minimizing any re-oxidation of the final liquid metal product before the molten metal is removed from the furnace a…

Making Slag - an overview | ScienceDirect Topics

05-04-2010· The smelting slag produced contains FeO and SiO 2 with their contents of 30–40% and 35–40%, respectively. The content for Al 2 O 3 or CaO in the smelting slag may go up to 10%. The smelting slag also contains copper with content of 0.5–2% in two forms, dissolved Cu 2 S in matte and entranced matte droplets.

24-05-2020· Slag is a byproduct of metal smelting, and hundreds of tons of it are produced every year all over the world in the process of refining metals and making alloys.Like other industrial byproducts, slag actually has many uses, and rarely goes to waste. It appears in concrete, aggregate road materials, as ballast, and is sometimes used as a component of phosphate fertilizer.

Basics of slag production - Article on the slag industry ...

Slag from the production of ferrochrome is also included here; this material is produced in substantial tonnages and the main use of ferrochrome is in the steel industry. Slags also arise from other processes, particularly the smelting of non-ferrous metals, but these materials can be very different and each needs to be studied individually.

Zinc smelting - Wikipedia

Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific ...

2 天前· 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 fluidized-bed type.

01-01-2020· A combination of smelting-reduction of bauxite and leaching treatment of the produced slag for alumina recovery is known as the Pedersen process. The process is considered to be more sustainable for producing metallurgical-grade alumina than the Bayer process as it does not produce bauxite residue (red mud), which is one of the most abundant industrial byproducts in the world.
