What is Slag? (with pictures) Info Bloom

Jan 27, 2021· Other compounds found in this material depend on the type of smelting. 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.

Ancient iron production Wikipedia

The ores used in ancient smelting processes were rarely pure metal compounds. Impurities were removed from the ore through the process of slagging, which involves adding heat and chemicals. Slag is the material in which the impurities from ores (known as gangue), as well as furnace lining and charcoal ash, collect. The study of slag can reveal information about the smelting process used at the time of its formation.

Recovery of the ferrous and non-ferrous metals and also the use of the pure 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 grain classes.

Nonferrous Slag an overview ScienceDirect Topics

Typical nonferrous slag contains 30–55% FeO, 30–45% SiO 2, and less than 10% CaO, although variations occur depending on the system in which the slag is formed ( Kokal, 2006 ). Nonferrous slags are sometimes classified as basic, acid, and neutral slag based on silicate degree. The silicate degree can be expressed as.
