Definitions

  • the treatment step may be selected to alter the properties, such as viscosity, of the water used in granulation step (b) .
  • TOTAL BLEND 100.00 One part of the sinter mix (the "trial sinter mix") was prepared with a sugar solution and the remainder of the sinter mix (the “base sinter mix”) was prepared without the addition of sugar. Details of the green bed properties, sinter plant operations, and sinter quality are set out in Tables 6, 7, and 8, respectively.

Abstract

L'invention concerne un procédé pour agglomérer par frittage un mélange de particules de minerais de fer, ce mélange comprenant des particules tendres/poreuses. Le procédé consiste à former un mélange brut de particules de minerai de fer et de fondant, à granuler le mélange brut avec de l'eau et à agglomérer par frittage le mélange granulé. Le procédé est caractérisé par une étape de traitement destinée à inhiber l'absorption de l'eau dans le minerai tendre/poreux.
