  3. Bottom-blown oxygen converter - Wikipedia

    en.wikipedia.org/wiki/Bottom-blown_oxygen_converter

    The Bottom-blown Oxygen Converter or BBOC is a smelting furnace developed by the staff at Britannia Refined Metals Limited (“BRM”), a British subsidiary of MIM Holdings Limited (which is now part of the Glencore group of companies). The furnace is currently marketed by Glencore Technology.

  4. Smelting - Wikipedia

    en.wikipedia.org/wiki/Smelting

    Electric phosphate smelting furnace in a TVA chemical plant (1942) Smelting is a process of applying heat and a chemical reducing agent to an ore to extract a desired base metal product. [1] It is a form of extractive metallurgy that is used to obtain many metals such as iron, copper, silver, tin, lead and zinc.

  5. Metallurgical furnace - Wikipedia

    en.wikipedia.org/wiki/Metallurgical_furnace

    A metallurgical furnace, often simply referred to as a furnace when the context is known, is an industrial furnace used to heat, melt, or otherwise process metals. Furnaces have been a central piece of equipment throughout the history of metallurgy ; processing metals with heat is even its own engineering specialty known as pyrometallurgy .

  6. Reverberatory furnace - Wikipedia

    en.wikipedia.org/wiki/Reverberatory_furnace

    Reverberatory furnaces (in this context, usually called air furnaces) were formerly also used for melting brass, bronze, and pig iron for foundry work. They were also, for the first 75 years of the 20th century, the dominant smelting furnace used in copper production, treating either roasted calcine or raw copper sulfide concentrate. [1]

  7. Cupellation - Wikipedia

    en.wikipedia.org/wiki/Cupellation

    16th century cupellation furnaces (per Agricola). Cupellation is a refining process in metallurgy in which ores or alloyed metals are treated under very high temperatures and subjected to controlled operations to separate noble metals, like gold and silver, from base metals, like lead, copper, zinc, arsenic, antimony, or bismuth, present in the ore.

  8. HIsarna ironmaking process - Wikipedia

    en.wikipedia.org/wiki/HIsarna_ironmaking_process

    The HIsarna ironmaking process is a direct reduced iron process for iron making in which iron ore is processed almost directly into liquid iron ().The process combines two process units, the Cyclone Converter Furnace (CCF) for ore melting and pre-reduction and a Smelting Reduction Vessel (SRV) where the final reduction stage to liquid iron takes place.

  9. Flash smelting - Wikipedia

    en.wikipedia.org/wiki/Flash_smelting

    Flash smelting (Finnish: Liekkisulatus, literally "flame-smelting") is a smelting process for sulfur-containing ores [1] including chalcopyrite. The process was developed by Outokumpu in Finland and first applied at the Harjavalta plant in 1949 for smelting copper ore. [2] [3] It has also been adapted for nickel and lead production. [2]
