  • Patent number: 6497746
    Abstract: A process for particulate agglomeration (i.e., pelletizing) and the product produced (i.e., pellets) by such processes are disclosed. The process generally comprises a process of agglomerating particulate material, said process comprising commingling said particulate material with a moistening effective amount of water, a binding effective amount of polymer and a binding effective amount of weak acid to produce a mixture and forming said mixture into agglomerates.
    Type: Grant
    Filed: March 15, 1993
    Date of Patent: December 24, 2002
    Assignee: Akzo Nobel N.V.

  • Publication number: 20020035188
    Abstract: Methods for agglomerating particulate material, especially iron ore and iron ore which is difficult or impossible to bind using known binders and techniques, by rendering the surface of the material negative, by chelating interfering elements in or on the material to permit effective performance of the binder, or by using a binding effective amount of a polymeric binder, sodium carbonate, sodium citrate, and, optionally, caustic.
