Title:
METHOD FOR AGGLOMERATING FINE PARTICLES
Document Type and Number:
WIPO Patent Application WO2004011577
Kind Code:
A3
Abstract:
A method for agglomerating fine particles, involves reacting urea, urea/formaldehyde condensate, a strong inorganic acid, preferably sulfuric acid, and at least one polyfunctional compound chosen from the group consisting of hydroxycarboxylic acids, dicarboxylic acids, and polyols (containing at least two hydroxy groups) in the presence of particles to be agglomerated to form a fine particle agglomerate. Optionally, molasses, p-toluene sulfonic acid, xylene sulfonic acid or resorcinol can be added to the binder solution.
