Get PriceAn improved air jig apparatus and method is disclosed in which a dry magnetic separator is used to separate paramagnetic and ferromagnetic minerals from the dust component of coal cleaned with the air jig. The cleaned product of the dry magnetic separator is combined with the cleaned product of the air jig thereby improving both the quality and the quantity of the unmodified air jig product.
Get PriceMagnetic separation of the iron oxide served as a first step to alleviate the iron contamination problem. However, the agglomeration of some iron oxide with alumina and silica made it difficult to completely separate the iron from the fly ash. Further iron separation was achieved by chlorinating the nonmagnetic ash fraction at 550°C for 30 ...

Get PriceThe optimum process parameters were proposed as follows: using lime as the additive, lignite as the reductant, weight ratios of vanadium tailings/lignite/lime at 100:30:10, reduction roasting at 1200°C for 60min, and particle size of 98% less than 30μm in the final roasted product feeding to magnetic separation.
Get PriceWhat Is Coal Preparation? • Coal preparation is the removal of undesirable material from the Run-of-Mine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities. Through coal preparation, a uniform product is achieved.
Get PriceMagnetic separation of raw coal and semicoke grinded up to particle size 0–0.5 mm was conducted in a laboratory magnetic separator in two steps—the first was at magnetic field induction of 0.35 T, the second—at 1.7 T.
Get PriceIn this paper, the improvement of Turkish lignites by semi-coking and REMS magnetic separation, in two stages, is discussed. The oxidation and decomposition of pyrite through the thermal treatment result in the formation of iron oxide and pyrrhotite on the surface. In addition to pyrite, part of the ...
Get Pricean increase in the selectivity of magnetic separation of thermo-treated lignite samples; 2. magnetic separation of non-pyritic and non-sulphatic sulphur with magnetic products (tailings). The suggested mechanism of two-stage thermomagnetic beneficiation of lignites must take into account these specific, experimentally observed phenomena.
