Abstract
In an iron ore pelletization process in which particulate ore is mixed with particulate polymeric binder in the presence of moisture and the mixture is pelletised, the particulate binder is a blend of ionic synthetic water soluble polymer, such as a copolymer of acrylamide and sodium acrylate having intrinsic viscosity 2 to 16 dl/g, with a larger amount of a guar gum.
Claims8
An ore pelletization process comprising providing particulate ionic synthetic water soluble polymer, providing particulate soluble natural polymer which consists essentially of guar gum, forming a mixture of particulate ore, moisture and binder by mixing particulate ore in the presence of moisture with a binding amount of particulate organic binder which consists essentially of 1 part by weight of the ionic synthetic water soluble polymer and 2 to 30 parts by weight of the water soluble natural polymer which consists essentially of guar gum, and pelletizing the mixture of particulate ore, moisture and binder.
