    OverviewOre smeltingAncient usesModern usesBasic slagSee alsoFurther reading

    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

  • Non-ferrous extractive metallurgy - Wikipedia

    History Prehistory of non-ferrous extractive metallurgy. In general, prehistoric extraction of metals, particularly copper, involved two fundamental stages: first, the smelting of copper ore at temperatures exceeding 700 °C is needed to separate the gangue from the copper; second, melting the copper, which requires temperatures exceeding its melting point of 1080 °C.

  • Ferrous metallurgy - Wikipedia

    Ferrous metallurgy is the metallurgy of iron and its alloys.It began far back in prehistory.The earliest surviving iron artifacts, from the 4th millennium BC in Egypt, were made from meteoritic iron-nickel. It is not known when or where the smelting of iron from ores began, but by the end of the 2nd millennium BC iron was being produced from iron ores from Sub-Saharan Africa to China.

  • 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.

  • What is Slag? (with pictures)

    2019-12-19  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 ...

    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.

  • Gold Smelting Refining Process

    Gold and silver form an alloy that is heavier than the slag and sinks to the bottom of the furnace. Once the smelting is complete, the slag is removed and the precious metals are casted in ingots. The slag contains gold and silver and must be reprocessed in order to minimize the losses of precious metals.
