Kinetics of High-Temperature Dehydration of Lisakovsk Iron Ore Concentrate

Abstract: Аннотация. Лисаковское месторождение бурого железняка (Кустанайская область, Казахстан) разрабатывается открытым способом, что обеспечивает более дешевую добычу руды. На фабрике ЛФ ТОО «Оркен» гравитационно-магнитным способом производят обогащение руды с получением гравитационно-магнитного концентрата, содержащего 48-49 % Fe, 10-12 % SiO 2 , 4,5-5,5 % Al 2 O 3 , 0,7-0,9 % Р. Полученный продукт поступает на агломерацию в АО «АрселорМиттал Темиртау» (г. Темиртау, Казахстан). Из-за повышенного содержания фосфора … Show more

“…The work on desalinization of preliminary roasted concentrate was carried out in a chemical laboratory of OJSC VNIIMPT [1][2][3][4] Table 1 it is seen that the residual content of phosphorus in the concentrate after sulphuric acid treatment minus 0.044 mm in size and minus 0.071 mm in size does not differ much (makes up on an average 0.18%, error limit of chemical analysis 0.024%). Based upon the obtained results given in Table 1 as optimal degradation size of the roasted ore 0.071 mm is accepted.…”
