Recovery of iron and calcium aluminate slag from …
Abstract A high-temperature reduction and smelting process was used to recover iron and calcium aluminate slag from high-ferrous bauxite. The effects of w(CaO)/ w(SiO 2) ratio, anthracite ratio, and reduction temperature and time on the recovery and size of iron nuggets and on the Al 2 O 3 grade of the calcium aluminate slag were investigated through thermodynamic calculations and experiments.
What is Slag? (with pictures) - wiseGEEK
15-4-2020 · 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.

US4046323A - Process for controlled slow cooling …
A process for controlled slow cooling of non-ferrous smelting slags, such as copper slags, for the recovery of the non-ferrous metals contained therein by subsequent crushing, milling and flotation operations is disclosed. The process comprises the steps of pouring the molten slag into a ladle, allowing the slag to slowly cool and solidify in the ladle at least to the point where a shell is ...

With smelting slags, two approaches are available in principle for recycling. Recovery of the ferrous and non-ferrous metals and also the use of the pure, metal-free slag itself as a secondary construction material. The recovery of the metals can be implemented using ferrous and non-ferrous metal separators adapted to different stone classes.

Slag: From Metals By-product to Valuable …
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.
