In this paper, we reviewed steel slag treatment, recycling, and management in China. Although China''s annual slag production reached more than 100 million tons, its utilization rate is only %.
With smelting slags, two approaches are available in principle for recycling. Recovery of the ferrous and nonferrous metals and also the use of the pure, metalfree slag itself as a secondary construction material. The recovery of the metals can be implemented using ferrous and nonferrous metal separators adapted to different grain classes.
metallurgical processes are treated and utilized in different ways based on the different slag characteristics. The most economic and efficient option for reducing the metallurgical waste generation is through recycling. Slag recycling has been successful in a variety of industries, for example, ironmaking and steelmaking. However, some
Slag Recyling (Waste and Recycling) Services in Asia. called ˝slag dump ˛ because the slag is the main metallurgical waste landfilled in cone shaped heaps (Figure 5) Between 1968 and 2006 the slag dump has been landfilled with about 3650 mil tons of blast furnace slag and approx 1450 milt of steel slag .
Slag recycling. With smelting slags, two approaches are available in principle for recycling. Recovery of the ferrous and nonferrous metals and also the use of the pure, metalfree slag itself as a secondary construction material.
Many types of metallurgical slag are very hard despite being brittle. As a result, singlestage crushing is not sufficient. Depending on the feed size and throughput requirements, we recommend using the rotor shredder (type RS) or impact crusher (type PB) for slag precrushing. Once this has been done, initial sensorbased sorting of the metal components can be performed if a high level of ...

Whether quickly cooled with water (metallurgical slag) or cooled slowly (lump slag), these are secondary raw materials in sectors such as the cement, insulation and road construction industries. Material recycling processes contribute significantly to the conservation of natural resources and environmental protection.
1. Introduction. Currently, the main source of zinc metal is the traditional zinc resource—zinc sulfide ores. However, as the zinc consumption increases and the zinc sulfide ore grades deteriorate, the gap between supply and demand has become a major problem for the zinc industry [1,2].At the same time, large quantities of metallurgical slag and dust (MSD) are constantly produced during the ...
In contrast to common BF operation, the metal and slag . Slag and ash: Machines for recycling incineration. Grate ash from waste incinerator plant and slag from metallurgical smelting processes contain significant proportions of iron and nonferrous metals that today can be efficiently recovered.
Aug 01, 2008· 1. Introduction. In pyrometallurgical processes slags are used to prevent oxidation of the metal through contact with air, to limit heat losses through radiation and to remove impurities from the molten metal (Engh, 1992, Slag Atlas, 1995).After the liquid slag is separated from the metal, it is cooled to ambient temperatures, either in a matter of seconds using water cooling in a granulation ...
Jul 18, 2013· With respect to steelmaking slag, emphasis has in recent years been placed on hot metal treatment before refining and ladle treatment after decarburisation. The bulk removal of silicon, phosphorous and sulphur from the hot metal product of the blast furnace by specially designed slags prior to refining in a basic oxygen furnace, has reduced tap ...
On a global scale, these slags are landfilled or used in lowvalue applications. Upcycling these slags to produce a sustainable cementitious binder, inorganic polymers, does not only substitute the vast CO 2 emitting Portland cement, but also gives economic motivation to metallurgical companies to invest in the valorization of their slags.
