  • recovery of high gradeironcompounds from ldslagby

    Jan 10, 2014 · The grinding of steel slag and magnetic separation are necessary for a better separation of a high grade iron compounds which can be directly recycled in converter steel mill. Even, milling at about 50 μm is not sufficient to release complete carrier iron and calcium due to the small size of the crystallites. Only wet magnetic separation is appreciate to obtain a sufficiently enriched product iron …

  • a physico-chemicalseparation process for upgrading iron

    Nov 14, 2013 · The physical separation process is a method that crushes waste copper slag and subjects the crushed material to oxidation reaction, followed by application of mineralogical technologies such as magnetic separation, eddy current separation and flotation, as well as leaching, thereby separating and recovering iron from the waste slag

  • cn103045777a - dry processing technique foriron

    The technique comprises the following steps: iron-containing steel slag powder is passed in a rotary drum dryer for drying, then is passed in a ball mill for dry milling, and is passed in a powder

  • separationof steelmakingslagwith mechanical stirring by

    In order to recover this iron, steelmaking slag is processed with various methods such as crushing, sieving and magnetic separating. Magnetic separators process steelmaking slag in multiple layers for mass production and non-magnetic particles are attracted to a magnet roll by magnetic particles [1]

  • optimization ofmagnetic separationprocess foriron

    Abstract 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

  • recovery ofironfrom wasteslagof pyrite processing

    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 various options for recovery of iron from the waste slag and select the most advantageous option for industrial trial which is roasting of the waste slag under …
