Slag metallurgy Britannica

Slag, by-product formed in smelting, welding, and other metallurgical and combustion processes from impurities in the metals or ores being treated.Slag consists mostly of mixed oxides of elements such as silicon, sulfur, phosphorus, and aluminum; ash; and products formed in their reactions with furnace linings and fluxing substances such as limestone.

Slag: From Metals By-product to Valuable Construction

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. (The ore beneficiation process at a mine is

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.

Relationship between copper content of slag and matte in

In the newly developed oxygen-enriched bottom-blowing copper smelting process (also known as the SKS copper smelting process), Cu loss in slag is one of the most concerning issues.

Smelting an overview ScienceDirect Topics

Smelting furnaces produce liquid Cu–Fe–S matte (usually 60–70% Cu), which must have its sulfur and iron removed to make copper metal. This is most frequently done in submerged-tuyere Peirce–Smith (Fig. 4) and Hoboken converting furnaces using air (often slightly O 2-enriched) as the oxidant.The process is similar to submerged-tuyere smelting except that the feed is molten matte, not

furnace produces a matte that contains desirable metals like nickel, copper and cobalt as well as a slag that is stockpiled on site and is managed to strict environmental standards. The furnace matte is then transferred to the converter aisle to further reduce the iron content and concentrate the pay metal content. The final product from the converter aisle is a matte containing 2% iron which

Slag is regarded as a by-product after it is separated from base metal or element in smelting furnaces or discharged from coal-firing boilers or municipal solid waste incinerators. Unlike normal primary product production in which the final required properties are carefully designed and adjusted during the production to meet the final products’ specifications, slag is produced with less

Secrets of the ancient iron smelting process. Iron casting was performed in structures described in archaeological literature as slag-pit furnaces. This type of furnaces is known from the territories of Central and Eastern Europe and their spreading was connected with the Germanic peoples and eastern Celtic tribes. A furnace consisted of two main parts, the lower one called a pit and the upper

ELECTRO SMELTING OF ILMENITE FOR PRODUCTION OF TiO

Ilmenite smelting is a carbothermic process to upgrade the mineral ilmenite, yielding TiO2-rich slag (which is mainly used as a feed stock for TiO 2 pigment production) as primary pr oduct and pig iron as a by-product. This smelting process is unusual in having slag as its primary product and metal as a by-product. Another unusual aspect of the process is that no fl uxes are added to control

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
