Oct 31, 2014· The soil-steel slag mixture is hazardous material and needs to be treated because steel slag has heavy metals, which can be leached out. Two types of soil sample from the landfill site, i.e., plain soil and soil sample after the soil-washing process, have been sampled and tested with the superconducting magnetic separation system.

To improve the efficiency of iron recovery from steel slag and reduce the wear-and-tear on facilities, a new method was proposed by adding a secondary screen sizer to the magnetic separation process according to grain size distribution of magnetic iron (M-Fe) in the slag.

In addition to cleaning, aging, and quality-control requirements, crushing, screening and magnetic separation are required to produce a suitable coarse or fine aggregate product. Consistency of gradation, unit weight, and absorption are important for steel slag aggregates to be used in hot mix asphalt, and the aggregate processor must ensure ...

The steel slag superfine powder production process comprises the steps that a coarse grinding device is used for conducting coarse crushing on steel slag tailings; the steel slag tailings subjected to coarse crushing are sorted by a screening magnetic separation device and then are divided into tailing fine powder and magnetic …

The invention relates to a steel-slag processing method, including the procedures of separation, magnetic separation, fine crushing, magnetic separation, ball-mill washing, etc. The slag and steel are separated by fine processing of waste steel slag, the iron content in the waste slag is lowered, the waste steel …

The iron that is present in steel slag can be recovered using many approaches, such as oxidation of the molten slag by CO 2 gas [9], carbon reduction [10,11] and magnetic separation [12, 13 ...

Sep 09, 2015· A process combined gravity separation and magnetic separation process has therefore developed to recover the iron in the slag . The obtained iron-containing fines contain up to 86 wt% Fe, and 78 wt% of total iron in the waste slag can be recovered through the process.

Feb 05, 2021· Magnetic Separation. The treatments carried out on a raw slag using medium and low magnetic intensity lead to the separation of a wüstite type mineralogical phase, mainly concentrated in the magnetic phase. Likewise, larnite (probably, substituted by iron) is concentrated in the magnetic phase at the end of the treatment as well as hematite.

Sep 12, 2019· Magnetic Drum Separator: Dry drum separators have been developed mainly for dry separation of ferromagnetic ores with particle sizes finer than 20 mm. In addition to this conventional application, the dry drum separator has found a wide range of other applications such as: Iron and steel slag treatment. Reduced pyrite ash separation.

Jul 28, 2016· Steelmaking slags are usually processed for iron recovery by dry magnetic separation. The recovered iron-rich products are recycled back into the ironmaking and steelmaking processes to replace high-cost 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 ...
