ferrous smelting slag

Slag - Wikipedia

In nature, iron, copper, lead, nickel and other metals are found in impure states called ores, often oxidized and mixed in with silicates of other metals. During smelting, when the ore is exposed to high temperatures, these impurities are separated from the molten metal and can be removed. Slag is the collection of compounds that are removed. In many smelting processes, oxides are introduced to control the slag chemistry, assisting in the removal of impurities and protecting the furnace refractorylining from excessi

What is Slag? (with pictures) - Info Bloom

Jan 27, 2021  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.

Copper smelting slag is a solution of molten oxides created during the copper smelting and refining process, and about 1.5 million tons of copper slag are generated annually in Korea. The oxides in copper smelting slag include ferrous (FeO), ferric oxide (Fe2O3), silica (SiO2 from flux), alumina (AI2O3), calcia (CaO) and magnesia (MgO). The main oxides in copper slag, which are iron oxide and ...

Nonferrous Slag - an overview ScienceDirect Topics

Nonferrous Slag. Nonferrous slags have little significant use as aggregate for concrete, although some phosphorus slags appear to be usable,307 and Rossouw et al.309 have indicated the conditional suitability for use in concrete of several types of metallurgical slag.

Slag: From By-product to Valuable Construction Material

Jul 29, 2014  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.

Borates in Metallurgy and Gold Refinement U.S. Borax

In the production of steel and non-ferrous metals, borates act as a flux during smelting. In this capacity, they are used to dissolve metallic oxide impurities, which are then removed with the slag. Borates are also used as a cover flux, to provide a protective barrier against air oxidation.

Aug 05, 2016  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.

Jul 31, 2020  The amount of copper flash smelting slag has increased during the recent years along with an increasing slag-to-metal ratio. During slag tapping, some copper sulfide is mechanically entrained. As a result, it is necessary to recover copper matte from the slag by suitable methods. At present, the most common way is slow, controlled cooling in a transfer ladle. However, research on

Slag - Infogalactic: the planetary knowledge core

The smelting of copper and lead in non-ferrous smelting, for instance, is designed to remove the iron and silica that often occurs with those ores, and separates them as iron-silicate-based slags. Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium , silicon ...
