  • Enhancement of Iron Recovery from Steelmaking Slag Fines

      Steelmaking slags are usually processed for iron recovery by dry magnetic separation The recovered ironrich products are recycled back into the ironmaking and steelmaking processes to replace highcost steel scrap and iron ores However, current slag processing is far away from optimum conditions, especially for slag fines with small particle sizes, resulting in generation of nonrecyclable Under the optimal conditions, 9367% iron from the raw ore was recovered in the form of iron nugget with 9544% iron grade After a water leaching process, 8561% of the vanadium from the roasting slag was leached, confirming the sodium oxidation of most of the vanadium oxides to watersoluble sodium vanadate during the roasting process The A method for recovery of iron, titanium, and vanadium from The iron/steel slag processing flow is schematically shown in Fig 2 Steelmaking slag is subjected to the following four processes: ① solidify and cooling of the hot molten slag, ② crushing and magnetic separation treatment of the slag to recover the metal iron, ③ crushing and classification of the slag for grain size adjustment to manufacture the slag product, and ④ aging treatment UDC 669 054 82 : 669 184 244 66 Processing and

    Grate ash or grate ash residues offer a high processing potential and can be used for the recovery of valuable secondary materials These are obtained from the incineration of household waste, sewage sludge and metallurgical products Over decades Loibl has manufactured conveyors for the slag processing Copper, iron, aluminum can be separated effectively from the slag and further Iron processing Iron processing Iron making: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this wayIron processing Iron making BritannicaIron processing, use of a smelting process to turn the ore into a form from which products can be fashionedIncluded in this article also is a discussion of the mining of iron and of its preparation for smelting Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive magnetic properties It constitutes 5 percent by weight of the Earth’s crust, and it is the Iron processing Britannica

  • Types of iron and steel slag : NIPPON SLAG ASSOCIATION

    Iron and steel slag refers to the type of metal manufacturing slag that is generated during the process of manufacturing iron and steel products The term "slag" originally referred to slag produced by metal manufacturing processes, however it is now also used to describe slag that originates from molten waste material when trash and other substances are disposed of at an incinerator facility  Steelmaking slags are usually processed for iron recovery by dry magnetic separation The recovered ironrich products are recycled back into the ironmaking and steelmaking processes to replace highcost steel scrap and iron ores However, current slag processing is far away from optimum conditions, especially for slag fines with small particle sizes, resulting in generation of nonrecyclable Enhancement of Iron Recovery from Steelmaking Slag Fines 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, reduction of environment impact and improvement of economical benefits to the related companies The objectives of the present work are focused on: compare Recovery of iron from waste slag of pyrite processing

  • Recovery of cobalt, nickel, and copper from slags, using

    The aim of a slag cleaning process is to maximize the recovery of valuable metals (such as Co, Ni, and Cu) in an alloy with the lowest possible iron content The amount of metallic iron produced should be kept to a minimum, as the more iron present in the resulting matte or alloy, the greater the cost of the subsequent hydrometallurgical separation of the valuable metals, and the resulting   Hightemperature waste heat from the iron and steel industry, as shown in Fig 1, are mainly stored in products, molten slag and waste gas Molten slag, as a kind of byproduct during the steelmaking process, is exhausted in extremely high temperature and thus, it carries a great deal of highgrade heat accounting for 10% of waste energy in steel industry and 35% of hightemperature waste A review of waste heat recovery technologies towards Metal recovery Harsco Metals Minerals Our slag processing plants are customdesigned for each application For carbon steel slags: after screening of slag materials our magnetic separation process ensures the highest level of metal recovery Through further crushing and screening, the scrap can be upgraded to highFe material formetal recovery plant from slag lindadekeusterbe
