    Slag metallurgy Britannica

    Slag byproduct formed in smelting welding and other metallurgical and combustion processes from impurities in the metals or ores being treated.

  • iron slag management process

    iron slag management process

    Blast Furnace Slag Material Description User. Blast furnace slag is a nonmetallic coproduct produced in the process. It consists primarily of silicates aluminosilicates and calciumaluminasilicates. The molten slag which absorbs much of the sulfur from the charge comprises about 20 percent by mass of iron production.

  • How iron is made material manufacture making history

    How iron is made material manufacture making history

    The process of extracting iron from ore produces great quantities of poisonous and corrosive gases. In practice these gases are scrubbed and recycled. Inevitably however some small amounts of toxic gases escape to the atmosphere. A byproduct of iron purification is slag which is produced in huge amounts.

  • Generation of iron and steel slag NIPPON SLAG

    Generation of iron and steel slag NIPPON SLAG

    Iron and steel slag can be broadly classified into blast furnace slag that is generated when iron ore is melted and reduced in a blast furnace and steelmaking slag that is generated during the steelmaking processes used to modify the components of iron.

  • Generation of iron and steel slag NIPPON SLAG

    Generation of iron and steel slag NIPPON SLAG

    Steelmaking slag is generated by the process that turns pig iron produced by a blast furnace into tough and highly workable steel. Converter slag is the oxidized material that is generated when lime and other auxiliary materials are added and oxygen is blown onto the pig iron in order to remove carbon phosphorous sulfur and other components.

  • Recovery of iron from waste slag of pyrite processing

    Recovery of iron from waste slag of pyrite processing

    Abstract A considerable amount of waste slag from the pyrite roasting process is produced every year. Recovery of iron from the waste slag is of great interest for maximum use of mineral resource.
