Abstract
The mined ore cannot be used in the metallurgical process without preliminary preparation. The main preparatory operation is ore size preparation. Small ore fractions (-5+0 mm) are carried out of the furnace during smelting and smelting becomes inefficient. Therefore, it is necessary to exclude fine ore grades and direct them to roasting. In this paper, loose iron ores were investigated and the feasibility of roasting this product was determined. The initial moisture content of the dough, the content of different grades of coarseness and elemental composition were studied by spectral and chemical method.
