  • Patent number: 4501775
    Abstract: The strength of ice is reduced by dissolving in water prior to freezing a composition of (A) a water-soluble polyhydroxy compound or monoalkylether thereof and (B) a water-soluble organic nonvolatile compound having a hydrophilic group such as amine, carboxyl or carboxylate groups in an amount to provide an effective amount, e.g., on the order of about 0.25-5 weight percent, of (A) plus (B) based on the weight of water. The method is especially useful for application to particulate solids, such as coal and mineral ores, which are shipped and stored in masses exposed to freezing temperatures. Any ice that is formed is physically weak and will not deter the unloading of the thusly conditioned particulate solids.
    Type: Grant

  • Patent number: 4025596
    Abstract: Finely divided mineral solids are pelletized by uniformly blending the solids with a binder consisting essentially of an aqueous film forming latex of a water insoluble polymer after which the blend is shaped and dried. The binder preferably also contains a water dispersible agglutinant, such as wheat flour or bentonite.
